If you haven’t installed a kitchen before you likely haven’t heard of cabinet jacks. Not sure if you really need one? Or, maybe you need help picking the right length cabinet jack priced to your budget. In this article learn what the best cabinet jack is and where else you can use one.

Lifting and holding cabinets in the air is hard work. 

Which is why on my last few cabinet installations I’ve used the FastCap UpperHand  to hold cabinets in place. And not only does it reduce the physical strain, these jacks make it easier to clamp, level and screw the cabinets.

Which means a BETTER quality cabinet installation.

In this article you’ll learn:

  • What a cabinet jack is
  • Choosing the right cabinet jack length (#1 issue for DIY installs)
  • Best cabinet jacks
  • How to use a jack
  • Who manufacturers jacks

What is a Cabinet Jack?

A cabinet jack is a specialty tool that will hold upper cabinets in place during installation. The jack incorporates large surface pads to provide stability and micro-adjustment knobs or levers to set the cabinet at a precise height. Since the weight is off the installer the shimming and screwing are made easier.

Cabinet Jack Features

When looking at what makes for the jack there are some obvious and subtle things to consider:

  • Maximum and minimum length
  • Weight support
  • Extendable lengths
  • Size of top and bottom pads
  • “Freestanding” vs. swivel heads
  • Reach for microwave and fridge cabinets
  • Brand reputation
  • Micro-adjustment of the lever or adjustment screws

When considering all of these, however, the #1 need is the right length. While all jacks differ in other areas, the wrong length will ruin your upcoming cabinet installation.

Best Cabinet Jacks

Choosing the right cabinet jacks requires understanding where you’ll start the installation from.  But not sure if it’s your first time installing cabinets? Well, you’ll almost always install the UPPER cabinet first. 

And, to make your choice of jacks simple and economical I recommend looking at the FastCap UpperHand. While one jack will work, consider picking up two for longer cabinets and extra stability.

1. FastCap UpperHand Cabinet Jack (28-60")

  • Neoprene grip
  • Easy-pump handle

  • Solid 6″ x 6″ Universal Foot

This cabinet jack is my choice for a DIY install due to it’s proper height and economical price point.

First, this jack has a wide base and top pad, supports heavy cabinets up to 150 pounds, and with a 28-60″ reach will work for almost all upper cabinet installations.

And hey, I own this cabinet jack, and here’s a few features I like about it:

    • Stands in place without falling over on large 6×6 pads
    • Heavy duty upper squeeze handle for adjustment
    • Micro-adjustment with positive grip top extension
    • Quick adjust tab to slide the jack to rough height
    • Top and bottom pads have a rubberized gripping surface
    • Extends from a shorter working range to longer with dual locking detents

A pair of these is ideal as you can set one under the already installed upper cabinet with a little tension for a firm ledge. And then set the next jack under the upper cabinet you are installing  after it is lifted in place.

The only downfall? Due to it’s maximum reach of 60″ it falls short for microwave and refrigerator cabinets. But hey, woodworkers are innovative right? Just set a base cabinet underneath the jack with a board as a resting place to reach those taller cabinets.

A FastCap Little Jack works great for a remodel or for updates to cabinets when the bases are already in place.

With a 6×6″ top and bottom pad these jacks will easily hold an upper cabinet in place. To use simply place on top of a board spanning the lower cabinet (or counter for finished kitchens). Then place the cabinet on top and use the lever to adjust the cabinet to it’s final height.

A Fastcap H2PCSystem jack will do more than just cabinets. With it’s 57-144″ reach this jack will help with crown molding, drywall and many other jobsite projects.

By adding another seven feet of reach FastCap has one of the longest cabinet jacks on the market. And with removable feet this jack will convert from a jack with 6×6″ pads to a support with 3×3″ articulating pads for finesse jobs like crown molding.

With it’s range of 57-144″ this helps it double as a drywall jack and can hoist anything from HVAC runs, joists, drywall, crown molding, decking and anything else you can fit on top of it. You can even use it apply pressure for gluing.

Key features:

  • Creating a dust shield
  • Mounting a laser level
  • Supporting drywall
  • Holding microwave or over-fridge cabinets
  • Crown molding
  • Window coverings

If you are planning to install your base cabinets first and just aren’t sure if you’ll use a cabinet jack later then this might be your best option.

For example, while other jacks are good at, well, jacking, the Rockwell JawStand will do both. While NOT as good of a jack (due to it’s design) it will offer up support and then turn into an outfeed support later.

  • Multi-purpose jack that does double-duty as a clamp, spreader, and lift
  • Easily lift base cabinets, install shims or adjust leg levelers
  • Use it to install heavy doors and flooring
  • Pack of 2 for maximum versatility

Last update on 2020-10-27 at 01:54 / Affiliate links / Images from Amazon Product Advertising API

A Jack of All Trades base jack will help shim and level base cabinets. And this often frustrating task needs all the help it can get.

What other kind of jack could there be? Leave it to FastCap to introduce a tool most cabinet installers may not even be aware of: the “Jack of all Trades” for base cabinets.

This jack isn’t the same style as others on this list as it’s meant to lift base cabinets. And typically just a fraction of an inch.

So why would I want this jack?

If you’ve knelt on the floor trying to grab a heavy cabinet and insert a shim at the same time you’ll know it isn’t the easiest job. This jack allows you leverage to lift the base cabinet slightly and then insert the shims.

How to use a Cabinet Jack

If you haven’t installed cabinets before it’s tempting to start with the base cabinets. 

But in most cases this will lead to more issues, heavy lifting in awkward positions and a potential for damaged base cabinets.

Why I Install Upper Cabinets First

I’m the kind of carpenter that doesn’t build things on the floor, lift things more than I need to or make a mess I don’t have to.

So it sounds tempting to use the base cabinets as a resting place for upper cabinets right? 

Well, unfortunately it creates a few issues:

  • You will be leaning over the 24″ deep bases for *everything*
  • Increased risk of damaging the base cabinets with your tools
  • Awkward lifting angles, even with a jack
  • And, to use a jack you’ll need a sturdy plywood base spanning the lower cabinets

But, if you’re adding a cabinet to an existing kitchen (rare!) there might be a few uses for a shorter jack.

Two Jacks are Better Than One

If you’re installing with a partner, you’ll have the luxury of being able to use two cabinet jacks instead of one.

And, by doing so, you’ll gain the advantage of stability as you start to install shims and screw the cabinets to each other.

Using a Jack by YOurself

With most upper cabinets maxing out at 48″ you’ll be able to lift the cabinet in place by yourself.

And that’s when a free-standing jack, like the UpperHand, is useful to allow you to lift and rest the cabinet in place.  Then once the cabinet is set:

  • Use the adjustment lever to set the height of the cabinet
  • Then, install screws into the adjacent cabinet
  • Insert shims as needed against the wall and screw the cabinet to the wall.
  • Release the jack

Seven other uses for a cabinet jack after the project is done

For $50-100 you’ll be able to re-use a miter saw, cordless drill or other cabinet installation tools.

But what will I do with a cabinet jack when the project is over?

Here are seven things you can use a jack for after the kitchen is installed:

  1. Use as a load bar in your truck to prevent shifting of cargo (the FastCap 3rd Hand works best)
  2. Make dust shields for drywall projects
  3. Hold microwave cabinets in place during installation
  4. For the taller jacks, like the T-Jak, hold drywall to the ceiling
  5. Use as a spreader for framing projects to nudge (or hold) walls in place
  6. Support laser levels for tile projects
  7. Hold deck beams in place during rough framing

Cabinet Jack and Claw

After you’ve set the cabinet on the cabinet jacks the next task is to install shims and cabinet screws. And that’s where the cabinet claw comes into play:

Now obviously the cabinet claw will only work for face frame cabinets, so for a frameless design you’ll want to consider the FastCap Jack of all Trades (above) that will provide a secure grip will the cabinet is installed. And it even doubles as a cabinet jack for base cabinets.

Frequently Asked Questions About Cabinet Jacks

Frequently Asked Questions

How do you hang upper cabinets yourself?

Upper cabinets are best installed using a cabinet jack that will hold the cabinet in place so your hands are free to screw the cabinet to the wall.

What is the best cabinet jack?

There are two types of cabinet jacks in this article and which one you choose will depend on your installation style.

How many cabinet jacks do I need?

For upper cabinets under 18″ you can use a single jack. However, for cabinets over 18″ two jacks will allow the installer to more easily balance the cabinet during installation. Due to most upper cabinets lengths at 24-36″ two cabinet jacks are recommended.

How do you use cabinet jacks?

With a cabinet jack, you can install cabinets using these steps:

  • Lift the cabinet into position
  • Position the cabinet jack underneath
  • Make height adjustments with the cabinet jack
  • Attach a cabinet claw or cabinet clamp to the adjacent cabinet
  • Level the cabinet
  • Install face frame or cabinet-to-cabinet screws
  • Install shims against the wall as needed and screw cabinet to the wall

Now without a cabinet jack you’ll be manually holding the cabinet in place during each of these steps. While I’m 6’3″ and have years of manual labor to make this job easier, if you’re tackling this as a DIY’er you’ll appreciate this small investment in your health.


For the price of a dozen cabinet knobs you can improve your cabinet installation with a cabinet jack – and use it for future projects.
