Best Heavy Duty Drawer Slides With Locks (72-inches, 500 pounds)

Heavy duty drawer slides are classified as drawer slides with up to 1000-pounds capacity or have lengths up 72-inches. Which makes heavy duty slides useful for industrial, RV and other specialty solutions. However, they are more costly than standard cabinet and furniture drawer slides that stop at 24-inches and move 100-pounds.  Popular slides include the brand name Hettich that support 500-pounds, rare 72-inch slides for RV and trailer pullouts, and YENOU budget heavy duty slides.

Standard duty drawer slides are great for furniture and cabinets. But their construction doesn’t allow them to support loads over 100 pounds. And, most have lengths up to 24-inches that don’t allow them to work in shop or industrial settings.

Before buying heavy duty slides, though, its worth know a few things about them:

  • Almost all are full extension side mounts with ball bearing construction
  • HD slides are noises than their whisper-quiet kitchen counterparts
  • Expect up to 3/4-inch side clearance on each side of drawer.
  • Locks are optional for these slides and allow keeping the slide closed or opened

Lastly, this style of slide is expensive as they start around $50 for a shorter slide and up to $400 for a heavy duty 72-inch drawer slide.

HD Slide Overview

Heavy Duty Drawer Slide Infographic

Odds are, if you are looking for heavy duty drawer slides with over 100-pounds capacity its for a unique drawer application. Perhaps it is an overloaded, wide drawer with short 16″ slides. Or, maybe it’s a 60″ deep RV slide that needs to hold 500 pounds.

Within this unique niche of drawer slides there are a number of name brand drawer slides, and a huge variety of imported slides to the US market.

Lastly, these slides are typically ‘non disconnect’ – which means you cannot detach them easily. But since they support massive weight loads it is unlikely you’ll need to.

Types of Heavy Duty Slides

Heavy Duty Slide

While a standard drawer slide is available in a variety of mounting types the heavy duty class of slides is predominately side mount.

Why side mounts?

Well, the first reason is stability gained through steel on edge. With extended length and weight capacity this style of slide isn’t only thicker at a standard 3/4-inches it is also taller in height to support thicker steel and heavier ball bearings.

But, there are features like locking, extra length and even some heavy duty slides with soft closing.

500 Pound Plus Drawer Slides

500 pound capacity

Standard drawer slides start out with a 50 pound capacity.

But with heavy duty slides you’ll find a variety of slides with ten-times the weight bearing capacity. 

Key features of this weight class of slide include:

  • 3/4″ side clearance
  • Lengths up to 72-inches (24-60″ the most common)
  • Side heights of 3-inches
  • Full extension

The downside of this style of slide is they aren’t quiet and they require a fixed installation where the drawer or shelf can’t be instantly removed.

Locking Heavy Duty Drawer Slides

Locking drawer slide

From custom tool pull-outs, gun storage in truck beds to pullouts in campers there is a specific reason many turn to heavy duty slides: they can be locked in place.

Besides extension lengths up to 60-inchdes this style of slide will generally hold 250-pounds and then firmly lock in place. Which, as you can guess, is a must on uneven terrain or for shelving that must stay in place during use.

Standard Duty HD Drawer Slide

Standard duty HD drawer slide

Not every heavy duty drawer or shelf requires a 500-pound slide.

And not every budget can afford slides that cost upwards of $250-400 each.

Which is where a middle-ground 250-pound class of slide exists that offers up a heavy duty weight capacity but at a budget price.  The disadvantages, though, are weight capacity typically decreases the longer the slide is (something to watch for in all slides).

Heavy Duty 1/2-Inch Clearance

Half Inch HD drawer slide

When it comes to heavy duty drawer slides the best way to ensure a proper fit and operation is to buy the drawer slide first. And then build your project.

While a standard drawer slide for cabinets and furniture requires 1/2-inch of clearance, most heavy duty are 3/4-inch or a minor metric adjustment from that. 

All of which means there are some projects that require a standard 1/2-inch clearance but offer a heavier duty build and weight capacity.

Bottom Frame Heavy Duty Slides

Bottom Frame drawer slide

When projects call for heavy duty support with a long travel woodworkers will turn to a bottom frame drawer slide. 

By mounting on the underside of the drawer box or cabinet frame these slides are invisible during operation. And, for existing applications, do not require a specific side clearance.

Lateral File Drawer Slides For Wide Drawers

Lateral File drawer slide

While not a popular style of slide a lateral file drawer slide excels at one thing: wide and heavy drawers.

As the name implies, this type of heavy duty drawer slide typically offers quick-release, 150-pound capacity and support for wide displays.

Common uses: display cases, file cabinets, furniture and custom shelving.

Extra Long Heavy Duty Slides (60 - 72 inches)

72 inch drawer slide

While one of the hardest drawer slides to find, a 72 inch drawer slide is also one of the most useful for:

  • Trailer pull-outs
  • Truck-bed drawer slides
  • Replacement RV slides

The downside? Long shipping timelines for a slide that just isn’t readily available.

Heavy Duty Drawer Slide Brands

With standard duty slides dominated by top brands like Blum, stepping up the weight capacity you’ll find top manufacturers like Hettich, TCH, Accuride and more offering slides. 

While most offer a similar range of lengths and weight capacity look for differences not just in cost but certification processes with cycle testing.

Hettich HD Drawer Slides

Heavy duty drawer slide - 500 pound capacity

Hettich is a leading brand in heavy duty drawer slides, and these Made in USA slides have been cycle tested with 390 pounds at 10,000 cycles.​

Key features:

  • Full extension
  • Maximum weight capacity of 500 pounds
  • Cushioned in/out stops
  • Lengths up to 60″
  • Ball bearing spacers to reduce noise

Also, you’ll need to allow for a 3/4″ clearance on both sides of the drawer or shelf (versus the standard 1/2″) plus 3″ vertical height of this slide.

Pros

Cons

Vadania Locking Slides

Heavy duty drawer slide - locking

Vadania is a newer brand to drawer slides but offers up a quality line of slides that are well matched to RV, woodworking or metal storage solutions. And, their line of locking slides is comprehensive from 20″ slides with almost 500-pound capacity up to 60″ slides with just under 300-pound capacity weight loads.

The downside to locking slides? Expect to pay almost double of what a standard slide would cost. In this type of heavy duty drawer slide the features come at a cost.

Pros

Cons

TCH Hardware: 250 Pound Budget Heavy Duty Drawer Slide

TCH Hardware heavy duty drawer slide

TCH hardware is a major distributor and manufacturer of heavy duty equipment and hardware

While other slides have a declining weight load, the TCH slide supports that maximum 250# capacity up to the popular 36″ depth.

Key features:

  • .75″ width and just over 2″ in height
  • Zinc coated
  • Full extension plus over-travel with 3 folds
  • 250 pound weight capacity
  • Hold-in feature to keep drawer shut
  • Lengths 12-36″

Like most heavy duty drawer slides, screws are not included. And if you haven’t guessed by now that’s because some applications call for small bolts vs. screws.

Pros

Cons

Accuride 9301 - 12 to 60" Heavy Duty Drawer Slide

Accuride heavy duty drawer slide

For industrial applications carrying generators or super heavy duty sliding shelves these slides were designed for wide drawers and heavy loads.

Key features of this drawer slide include:

  • Full extension
  • Maximum weight capacity of 600 pounds
  • Lengths up to 60″
  • Ball bearing spacers to reduce noise

For more check out the Accuride 9301E technical sheet.

Pros

Cons

Vadania 1/2" Side Clearance Heavy Duty Slide

Vadania half inch side clearance heavy duty drawer slide

With most heavy duty drawer slides requiring a 3/4″ side clearance there are limited options for updating existing 1/2″ side clearance drawers.

But, these Vadania VA1551 slides are an option worth considering from a growing distributor of slides. And at a budget price.

Pros

Cons

Blum - Undermount Heavy Duty Drawer Slides

BLUM heavy duty soft close drawer slide

For drawers up to 125 pounds a heavy duty Blum undermount will offer soft close action as well.

I only install the Blum undermount soft close in my new cabinet and furniture projects. 

So when it comes to a slightly heavier duty slide (the standard slides are 100#) this HD version will give that extra pull to operate the soft close mechanism.

Key features:

  • Soft close engages at 2″ from closed.
  • 125 pound capacity per drawer
  • Drawer slides are not visible to the user
  • Blum durability and brand reputation

Pros

Cons

Lontan 4502S3 Heavy Duty Soft Close Slides (100#)

Lontan heavy duty drawer slide

For drawers up to 100 pounds a heavy duty Lontan side mount slideoffers soft close action as well.

Pros

Cons

Vadania Soft Close Heavy Duty Drawer Slide

Vadania heavy duty soft close drawer slide

If you haven’t used a soft close drawer slide you’ll want to consider investing in one. 

Even though heavier drawers may be less prone to the hard slam of a lighter drawer, having a spring-assisted closing is a great feature. And, in my standard duty drawer slide reviews I’ve found Vadania to be a solid quality closer.

Pros

Cons

Extra Long Drawer Slides

While weight is one factor, like the Fulterer 1000# slide, many forget that length of the drawer slides is another dimension that needs to be considered. 

And is often the reason for the added weight capacity.

Considerations for long drawer slides

In my experience any drawer slide over 24″ is an extra long drawer slide.

In fact, as slide lengths pass 24″ and widths creep over 30″ a lot of factors start to come into play:

    • Will the slide handle the torque when fully extended?
    • And is the cabinet properly anchored?
    • What about the slides rating at full extension?
    • Should I use bolts instead of screws?

36" heavy duty drawer slides

A 36″ heavy duty slide is one of the most popular sizes. While I’ve used these in fireplace surround cabinets, there are applications for kitchen islands, garage shelving, industrial applications and countless others.

Available features by manufacturer:

    • Accuride 9301E 36-inch  – 600 pound capacity, non-disconnect, slide weight of 24 pounds
    • Vadania A2576 36-inch – with extension to 72″, 396 pound capacity and subjected to 100,000 push/pull tests (per manufacturer). 
    • Hettich 36-inch  – with 500 pound capacity, 3″ height and cushioned stops for quieter operation.

60" drawer slides

Have an ultra heavy duty drawer that needs to extend five feet out and still support a massive load? While there are very few slides on the market, this 60-inch 500 pound slide  will provide the extension and weight for most projects.

Guide to Heavy Duty Drawer Slides

What is a heavy duty drawer slide?

A heavy duty drawer slide is a drawer slide rated for over 100 pounds. While many slides have a maximum capacity of 100 pounds, heavy duty drawer slides start at 125 pounds and typically have a capacity of 200 to 500 pounds. 

Due to the added weight these slides are typically side mount ball bearing slides. Additionally these slides have longer extension – with some up to 96″ and 1000 pound capacities.

When should I use a heavy duty slide?

There are  surprising number of uses for a heavy duty drawer slide. 

Here’s a few examples:

    • Trash roll-out bins in kitchen cabinets
    • Garage shelves with extensions over 24″
    • Custom truck bed roll-outs (extensions up to 72″ and 1000 pounds)

Buying Guide for the Best Heavy Duty Drawer Slides

As with all types of drawer slides, purchasing the slide itself is only part of the process.

What else should you think about with heavy duty slides? Well, consider these needs for your project:

Screws and Bolts Not Included With Heavy Duty Slides

Some heavy duty drawer slides will be used in metal applications like garage or industrial shelving.

While other slides will be used in furniture or garage workbench applications and require wood fasteners.

So whichever project you plan it’s important to note you won’t likely receive screws or bolts with your slides. But that’s easily remedied by purchasing the slides in advance and checking the clearance of the slide vs. the desired screws or bolts you’ll use.

For wood applications a popular screw is the #10 flat head for the cabinet (buy as long as possible) and a #10 pan head for the drawer side.

Even Heavy Duty Drawer Slides Need Jigs for Installation

While all ball bearing drawer slides are tricky to install, the heavy duty slides offer a weighty twist. Yep they are hard to hold and align.

And while I recommend a drawer slide jig for all drawer slides a jig is a must have for heavy duty slides.

Finding Hardware for Heavy Weight Drawers

When you have 200+ pounds of drawer and cargo to pull out you’ll need some heavy duty drawer handles.

Here’s a few I’d recommend taking a look at:

  • TCH Hardware spring loaded
  • JQK spring loaded stainless
  • Lizavo 6-1/2″ handles

Of course, what style you need will depend on the drawer construction and purpose. But planning ahead for the pull will keep our options open.

Frequently Asked Questions for Heavy Duty Drawer Slides

Most heavy duty drawer slides require at least 0.7″ versus the standard 0.5″ found on other drawer slides. Because of this, it is important to purchase your heavy duty drawer slide first, and then make the drawer or shelf it will carry.

Heavy duty drawer slides are almost always a side mount ball bearing slide. There are a few exceptions, like the Blum Heavy Duty under mount but they have a lower overall capacity.

Yes, a number of heavy duty drawer slides feature a locking mechanism to keep the drawer opened.

What's the maximum length of a heavy duty drawer slide?

Heavy duty drawer slides can be found out to 72″ (and some longer) in a variety of lengths.

Conclusion

Searching for the best heavy duty drawer slides takes a bit more research versus more standard drawer slides. And, if you decide your drawers won’t require over 100 pounds you can always fall back to the popular soft close drawer slides.

13 thoughts on “Best Heavy Duty Drawer Slides With Locks (72-inches, 500 pounds)”

  1. Thank you for pointing this out! With COVID a few products have disappeared and this was an oversight. I have updated this article with a (hard to find) 72″ slide for your reference.

  2. Great content for those of us deep into this rabbit hole. Cheers.

    Has anyone found a product or clever way to combine a heavy duty handle with the “release” of the lock tabs on the HD slide hardware. I got the updated Fulterer 450# locking sliders and the lock release pushes down rather that up to release. There’s obviously one on each side and I have found it awkward to always need to depress both and pull out at the same time, kinda making the handle I’ve installed useless until the drawer is already on it’s way out. I’ve seen some rope and eye-bolt configurations but I guess I’m just wondering if there was something more discrete and low profile. Appreciate any advise or insight. Thanks again.

  3. Adam – this is a great question. I did some digging and shy of a lever as you suggest haven’t found anything. Similar in concept to the stabilizer bars on wider drawers to keep things in motion together, but with a movement to unlock the slide.

  4. Missed the part about 1/2″ side mounted heavy duty(preferably rated @200-250lbs ea) 16″ slides
    for a 48″ wide drawer. Any heavy duty 16″ drawer slides I find only suggest a max 42″ wide drawer. Have replaced 3 times already and no success over a year of use yet. Have spent hours online looking for this Holy Grail ending in failure every time. It is only drawer in my box that is suitable in size for my sockets(and jeez do I have allot of sockets so it the most used drawer in my box daily)
    Drawer Dimensions 16″id deep x 48″ wide x 3 1/2 tall
    Slides 16″ closed 31″ fully extended.

  5. Hi Deano,

    Thank you for submitting this question. I haven’t seen a 1/2″ slide with a rating over 150 pounds – but I did update this article to include one as it was missing.

    Other than rebuilding your drawer to support a 3/4″ side clearance there aren’t many options. The 600 pound capacity Accuride do lay flat, at a less capacity if those are a retrofit option.

    Best,
    Eric T

  6. hello , I am looking for two sets of drawer slides for a spice rack on each side of micro wave.
    Since the micro wave protruded 4 inches from the cupboards ,i am looking for 10″ slides 1/2 “clearance but the slides must extend 4 ” past the regular full opening.

    Can you supply such slides

    Thanks

    Hubert

  7. Hi Hubert,

    That’s a unique application and I haven’t seen a slide that will do this. You could, however, use an “articulating box” with double the slides where a frame would pull out first, then another slide would extend past the microwave with the spice racks. You could consider mounting one slide flat or use a pantry (overhead) slide.

    Best,
    Eric

  8. I am looking for a full extension drawer slide for a really wide drawer sounds like the same project Deano is working on. A toolbox with a wide (48-52) inch drawer with a 5 inch height and 22 or 24 inch depth. Since I am at the beginning I can use 1/2 inch or 3/4 inch wide slides. But most if not all say they cannot do that width. Yet virtually every large tool rolling base found in mechanics shops has a large drawer like that with full extension slides. I would have to assume they are ball bearing as well. They are mounting 3 drawers on top of each other 4 or 5 inches and two shallower drawers like 2 inch tall. but full width. PLease take a look at the offering by rockintoolboxes of the extreme tools RX552512RC. Those top 3 drawers have got to be near 52 inches wide as the whole thing is 55 inch long. Any idea what they use. Then there are SnapOn, Milwaukee, and several others just to name a few. All with really wide drawers at the top of their rolling chests. Used for sockets.
    My project is entirely in wood. Plan on using 3/4 inch baltic birch for the sides/front and back of the drawers and 1/2 thick baltic birch for the drawer bottoms. (dimensions approximate as they use metric).

  9. Hi Brian –

    For wide drawers you can use a stabilizer kit like the 4180-0753-XE that pairs with the Accuride 3160EC slides. The reason for the stabilizer is to reduce wracking and keep the slides aligned. This combo of slides and connector kit are the only slide on the market for ultra-wide drawers.

    Thanks,
    Eric

  10. Hi Eric,
    Thanks for getting back to me so quick. The stabilizer kit appears to be only for undermount. Is there a product for side mount slides. I was planning on having an opening in the carcase for THREE drawers that are super wide with no in between drawer surfaces.
    Fortunately, I am at the beginning of this project so I can made changes on paper.

    Brian.

  11. Hi Brian –

    The two options I see are making the drawers narrower; or buying a 250 or 500-pound slide and testing out the motion with a fully loaded drawer.

    Note, however, that 60-inch wide drawer may have its own structural issue (especially the bottom). Narrower drawers may make more sense.

    Thanks,
    Eric

  12. Eric,

    I was almost expecting to use a slide with much higher ratings that I need. So a 500 # slide would be ok. As for the drawers, I intend to make them out of 3/4 inch Baltic Birch plywood. That is strong and stable stuff. The bottom will most likely be 1/2 inch Baltic Birch ply also. The carcase will also be made of baltic birch but multiple pieces thick laminated together. So it will be much stiffer than any normal cabinet.

    Thanks for your input so far.

    Brian.
