Looking for a drawer slide to hold heavy drawers or shelving? But not sure how to find best heavy duty drawer slides for your job? To help your search, in this article we’ll cover the major brands, weight loads from 100-600 pounds, lengths to 72″ and other features.

Don’t need over a hundred pounds of weight rating? Head over to our guide to medium duty soft close drawer slides instead.

I grew up in a machinists shop where my dad had a massive welding table. As in a 36″x60″ mass of concrete stressing 1/4″ plate steel that took years of abuse and building without a ding. And, under this five foot wide table, was a single drawer with dozens of vise-grip clamps, a few years supply of welding rods, flux, wire feed spools and magnets. 

While he had, as a metalworker, the tools, time and skills to custom fabricate his own slides for this 250+ pound drawer back in the 1970’s you might not.

But, fortunately, there are slides now available on the market that offer similar capability without the investment in build time (or know-how).

In this review we’ll cover a variety of heavy duty slides with load capacity up to 600 pounds, locking features and extensions to 72″. And these are perfect for projects from wide drawers to sliding shelves and truck box storage.

1. Hettich 3320 Heavy Duty Drawer Slide

Editor Choice With 500-pound Capacity

Hettich 500 pound heavy duty drawer slides

The Hettich 3320 Slide* is my pick for maximum load support as it comes in lengths from 12 to 60″ and supports a massive 500 pounds.

For industrial applications or that unique woodworking project these slides will not disappoint in maximum load capacity.

Key features of this drawer slide include:

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

The only drawback to this slide? It lacks a locking mechanism to hold the slide open.

A few key installation considerations include you’ll need to allow for a 3/4″ clearance on both sides of the drawer or shelf (versus the standard 1/2″) and allow for the 3″ vertical height of this slide. Also, screws aren’t included and need to be equally heavy duty.

2. Vadania Heavy Duty Slides With Lock

Locking Slide with 150-260 Pound Rating (variation by extension length)

Vadania 150 to 260 pound capacity drawer slide with locks

The Vadania HD Locking* slide is a heavy duty slide with built-in locks. This slide is great for those mid-range projects that require more weight support than a standard slide but not the 500# capacity of the full HD versions.

Having a lock on a full extension drawer slide is a must when you want the load it is carrying to stay out and accessible. Due to their design and 2″ height these are great for use in furniture, desks, custom truck drawers, or even garage shelving for pull-out access.

Key features of the Vadania drawer slide:

  • Full extension with 3 folds
  • Maximum weight capacity of 150 pounds (32″) up to 260 pounds (12″)
  • Cushioned in/out stops
  • Lengths up to 32″
  • Lock to secure drawer or shelf it supports open (or closed)

Of note, these slides require a slightly off-standard 0.7″ of side clearance per drawer and installation instructions can be found here.

3. TCH Heavy Duty Over Travel Drawer Slide

Best Value and Mid-Range Weight at 250 Pounds

TCH 250 pound heavy duty drawer slide

The TCH 250-pound slide* fits the niche for a non-locking economy priced heavy duty slide with up to 250# of capacity up to 36″.

While the previous slide on this list has a declining weight load it is almost a standard duty slide at 32″. But this 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.

4. Accuride 9301 Heavy Duty Drawer Slide

Massive 600-pound Capacity

The Accuride 9301E* is a heavy duty slide from the leader in drawer slides. And these non-disconnect slides lead the pack at 600 pound capacity.

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.

5. Blum Undermount Extra Heavy Duty Slides

Heavy Duty 125# Slide with Soft Close (vs. standard 100-pound version)

Blum extra heavy duty drawer slides

These Blum Heavy Duty Undermount* will conceal the slide and offer a premium soft close feature for drawers up to 125 pounds. And for almost all cabinet and even file drawers it’s tough to get that much weight in a drawer.

I only install the Blum undermount soft close in my new cabinet and furniture projects. And if you’re curious on why you can read more in my guide to the best soft close drawers.

So when it comes to a slightly heavier duty slide (the standard slides are 100#) this one 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

The only downside? These are pretty expensive slides and you’ll want to consider the value of concealing the slide. Also note they require a custom side fit (less than 1/2″) and require a custom drawer construction.

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

Lontan heavy duty drawer slides

The Lontan soft close slides* are my budget choice for slow close slides. And at a 100-pound weight capacity might have just enough capacity at an affordable price.

Maybe you don’t need a 500 or even 250 pound slide. Well, if that’s the case then a 100 pound rated slide is one of the more popular slides available. And after testing a number of leading ball bearing slides I like the Lontans.

Key features:

  • Standard 1/2″ side clearance (per side)
  • Soft close with dual spring
  • 100 pound capacity
  • Quiet operation

The only downside? The soft close might not work on wide drawers or as well when you reach full capacity.

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:

60" drawer slides

There are a number of 60″ drawer slides available, but the price almost doubles for this length.

And while that makes sense with twice the slide and heavier gauge metal it does make for a hefty price. For example, this Hettitch 60″ drawer slide* is one of the most expensive drawer slides on the market (as are comparable brands).

Guide to Heavy Duty Drawer Slides

#1 - 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.

#2 - 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

Heavy duty screws

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.

If you haven’t invested in a jig you’ll find Kreg jigs* are some of the most adaptable on the market.

Finding Hardware for Heavy Weight Drawers

Heavy duty drawer handle pulls

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.

Tools for Installing Heavy Duty Drawer Slides

There’s always an excuse to buy another tool. Sometimes it depends on the project and special needs, like these considerations when building heavy duty drawers:

  • For wood drawers you’ll want to use dovetail joinery and a high capacity jig like this Leigh 24″*. And yes that means it will handle a board up to 24″ wide.
  • Heavy duty plunge router*
  • Powerful cordless drill*
