DeWalt Adjustable Leveling Floor Mounting Plate Kit for Industrial Storage Rack (4-Pack)

Why I added the leveling kit to my racks

My garage slab isn’t even close to flat. A 10-foot run drops almost an inch and ripples in a few spots where the original pour wasn’t troweled perfectly. That doesn’t matter to a lawnmower, but a tall, heavily loaded industrial shelving rack can feel tippy and hard to square. I picked up DeWalt’s leveling plate kit to replace the standard plastic feet on my steel rack uprights and give myself a stable, anchorable base.

The kit is simple in concept: four heavy steel plates with threaded leveling feet that bolt to the bottom of the rack uprights, each with three holes so you can anchor them to concrete. Each foot adjusts independently with a generous 7 inches of range (with a minimum lift of about 0.7 inches), so you can tune out both slope and localized dips. It’s a smart upgrade for anyone working on uneven concrete or who wants anti-tip protection beyond wall straps.

Design and features

DeWalt kept this straightforward and robust:

• Four steel plates replace the glass-filled nylon feet that ship with compatible racks
• Threaded adjusters on each plate for independent height control
• Three anchor holes per plate to triangulate the load into the slab
• A hardware pack with concrete wedge anchors for floor attachment
• Black/chrome finish that matches the rack hardware

Each plate measures roughly 9.7 x 3.9 x 3 inches, giving you a stable footprint without adding much projection beyond the upright. The adjusters have enough travel to handle a significant slope, though in practice you’ll get the best stability with the least extension you can get away with. The set supports one four-post rack; if you plan to kit out multiple racks, budget one kit per unit.

Compatibility matters. The plates are designed for DeWalt’s heavy-duty racks—specifically the DXST10000 (all dates) and the DXST4500/DXST4500-W built after November 2018. If your 4500-series rack is older, check the production date before you buy.

Installation on a real slab

I installed the kit on a 72-inch-wide rack that was rocking on a shallow depression and later added a set to a 48-inch rack in the basement where the slab noticeably crowns toward a floor drain.

The process is straightforward:

1. Empty the rack and tip each upright enough to remove the factory plastic feet.
2. Attach a leveling plate at each upright base. The kit’s hardware focuses on floor anchoring; the swap at the upright is a direct replacement of the foot.
3. Reassemble the rack upright and set the unit roughly where it will live.
4. Use a spirit level or laser to dial in height on each adjuster, working corner-to-corner until the posts are plumb and the shelves are level.
5. Mark the anchor holes, move the rack aside, drill the concrete, vacuum the dust, and set the wedge anchors.
6. Roll the rack back into place, drop the plates over the anchors, snug everything down, and recheck level before final torque.

If you can, wedge the rack temporarily to reduce the amount of adjuster extension you need. Less extension lowers the center of gravity and makes the whole system feel more planted. With my 72-inch rack, I only needed about 1/2 inch of lift on two corners; the feet turned smoothly and held their height after tightening the locknuts.

Drilling concrete is the messy, time-consuming part—there are 12 holes total. A rotary hammer makes it bearable; a standard hammer drill will do it, but expect longer holes and more dust. I recommend a vacuum at the drill site and eye/ear protection. If your slab is post-tensioned or you’re unsure what’s beneath, get it scanned first. This kit is purpose-built for solid concrete; it’s not intended for wood, tile over backer, or hollow masonry without appropriate anchors.

Stability and day-to-day use

Once leveled and anchored, the difference in rack behavior is immediate. Load transfer moves from the small contact patches of the plastic feet to a broader steel plate, and anchoring locks out lateral creep that can show up when you’re pushing bins or sliding totes. On my garage rack, the annoying “teeter” that would show up at the middle shelves disappeared. In the basement, the 48-inch rack used to feel like it wanted to walk when loading the top shelf; with the plates installed and anchors set, it behaves like a fixed installation.

The 7-inch adjustment range is generous, but there’s a practical sweet spot. For heavy loads, I try to keep extension under an inch whenever possible. The steel plates themselves are stout, and the adjusters are confidently sized, but levering a fully loaded, wide rack far off the slab isn’t smart practice. Use the adjustment to correct modest unevenness and slopes; if you need inches of lift on one corner, consider fixing the floor or relocating the rack.

Build quality and hardware

Fit and finish are what I expect from DeWalt’s industrial rack line. The plates are flat, edges are clean, and the finish resists scuffs during install. The adjuster threads were cut cleanly on my set and rotated with fingertip force under no load. I added a touch of light oil to the threads before final leveling; it’s not required, but it helps prevent galling and keeps adjustments smooth down the road.

The wedge anchors in the box are appropriate for medium-duty anchoring in sound concrete. Each plate uses three, and the kit includes exactly 12—no extras—so avoid losing any during install. If any anchors look dinged from shipping or don’t spin on by hand, I keep a few spares in the shop to avoid delays. There’s no corrosion-resistance rating noted; for damp spaces, I’d keep an eye on the hardware over time and apply a protective spray if needed.

Compatibility and constraints

A few considerations from my installs:

• These are designed for DeWalt’s DXST10000 and newer DXST4500 uprights. If your rack is older 4500-series, confirm the production date. The hole pattern and foot design changed.
• The included anchors are for solid concrete. If you’re on brick, block, or an elevated deck, consult an engineer or use anchors rated for your substrate.
• Raising the rack increases the center of gravity. Minimize extension, and always anchor if you level more than a fraction of an inch.
• If your floor is nearly level and the rack only rocks slightly, a rigid shim may be enough. The kit shines when you need adjustability and anchoring.

Tips for a cleaner install

• Level before you drill. Get the rack dialed in and mark holes with a transfer punch or tight pencil.
• Use a rotary hammer and a sharp bit matched to the anchor size. Vacuum the hole thoroughly so the wedge seats correctly.
• Snug all anchors loosely first, recheck level, then torque to spec starting with the high corner.
• Add a paint dot to each adjuster and locknut so you can visually confirm nothing has moved during periodic checks.
• Don’t skip PPE: drilling concrete throws silica dust and noise.

What could be better

The kit does what it’s supposed to do, but there are a few things I’d like to see improved:

• Include one or two spare anchors. With three per plate, there’s no redundancy.
• A note in the box about maximum recommended adjuster extension under load would help users make better decisions, especially on wide racks with top-heavy loads.
• Optional corrosion-resistant hardware for damp basements or garages would be a welcome variant.

None of these are deal-breakers, but they’d polish an already solid accessory.

The bottom line

The DeWalt leveling plate kit is a practical, well-executed solution for stabilizing heavy-duty racks on imperfect concrete. Installation takes some time—most of it drilling—but the payoff in stability, safety, and everyday usability is real. The generous adjustment range and three-point anchoring give you control over both level and lateral movement, and the steel plates feel like they’ll outlast the rack.

Recommendation: I recommend this kit for anyone running compatible DeWalt industrial racks on uneven or sloped concrete, or for anyone who wants the added safety of floor anchoring. If your floor is dead flat and you never load the upper shelves heavily, you can get by with the factory feet and an occasional shim. But if you’re fighting wobble, working in a garage or basement with a less-than-perfect slab, or planning to load the rack near its rated capacity, these mounting plates are money well spent. Keep the adjuster extension modest, anchor all four corners, and you’ll have a rack that behaves like a permanent installation without giving up the flexibility to move it later.
