Best Low-Profile Truck Tool Boxes
See what a lower lid really changes—and what it does not. Compare three documented crossover layouts before giving up bed space.
Compare Current Options“Low profile” describes how the lid sits relative to the bed rail. It does not mean the whole box is shallow, and it does not prove compatibility with a folding cover, bed rack or trailer setup. The useful comparison is the combination of lid position, tub geometry and the floor space you lose.

01 Quick picks by bed-space priority
These are specification-led choices, not laboratory rankings. The available manufacturer evidence supports comparing these three clearly identified configurations rather than padding the list with unverified variants.
A slim fore-aft footprint is the main reason to choose this model: it preserves more usable bed length than a full-depth crossover.
This is the larger-volume counterpart to the slim UWS: better for bulky gear, but it consumes noticeably more front-bed depth.
The angled tub addresses bed-shape constraints while providing generous storage; it requires particularly careful lower-tub measurements.
02 Compare the physical footprints
Dimensions below are manufacturer-listed overall dimensions for the named model, not measurements taken on a vehicle. Confirm the current part drawing and mounting instructions before ordering.
| Model | Overall dimensions | Published volume | Primary benefit | Tradeoff |
|---|---|---|---|---|
| UWS EC10842 Deep Slim Low-Profile | 70 × 12.75 × 18.5 in overall | 6.1 cu ft | Best for tight front-bed space | The narrow tub may not hold bulky cases; a low lid does not mean the entire box is short. |
| UWS EC10802 Deep Low-Profile | 70 × 20 × 18.75 in overall | 10.8 cu ft | Best for bulky tool storage | You need the slim footprint of EC10842 or are assuming a low-profile box fits under your tonneau. |
| UWS TBSD-72-A-LP Deep Angled Low-Profile | 73 × 20 × 18.75 in overall | 11.2 cu ft | Best for angled bed clearance | Your truck lacks clearance for the 73-inch overall upper length or needs a narrow box. |
03 Detailed recommendations and ownership limits
The right choice depends on what you carry and which part of the bed you can afford to occupy. Each option below has an official UWS model page.
UWS EC10842 Deep Slim Low-Profile
A slim fore-aft footprint is the main reason to choose this model: it preserves more usable bed length than a full-depth crossover.
What stands out: UWS lists a RigidCore foam-filled lid, aluminum construction and low-profile configuration.
Who it suits: Full-size truck owners who need a compact front-to-rear footprint.
Ownership tradeoff: Measure tool-case depth and wheel-well-to-bulkhead clearance before choosing slim.
Check PriceUWS EC10802 Deep Low-Profile
This is the larger-volume counterpart to the slim UWS: better for bulky gear, but it consumes noticeably more front-bed depth.
What stands out: UWS specifies a 20-inch overall front-to-rear dimension, a foam-filled lid and 10.8 cubic feet of storage.
Who it suits: Owners prioritizing storage volume while keeping a lower-on-rail lid.
Ownership tradeoff: Check rail spacing, tub clearance and lid opening arc; published overall dimensions are not mounting clearance.
Check PriceUWS TBSD-72-A-LP Deep Angled Low-Profile
The angled tub addresses bed-shape constraints while providing generous storage; it requires particularly careful lower-tub measurements.
What stands out: UWS documents an angled tub, sliding organizer tray, dual-side paddle handles and a MicroSeal lid gasket.
Who it suits: Full-size pickup owners whose bed shape benefits from an angled tub design.

Check Price04 Five checks before ordering
- Top span: measure the actual rail-to-rail and outer-rail distances at the proposed mounting point. A nominal “69-inch” box can have a different published overall length.
- Lower tub shape: compare the manufacturer’s tub width and length—not only the top lid dimensions—with wheel wells, bed taper and front bulkhead.
- Fore-aft floor loss: mark the stated overall depth on the bed floor with tape; test whether long cargo and tool cases still load as intended.
- Opening arc: check the lid with the cab, rear glass, headache rack, tonneau rails and any camper-shell hardware. A low lid is not automatically a cover-compatible lid.
- Payload and mounting: account for box weight plus tools, follow the model-specific hardware instructions, and confirm trailer-related clearance where applicable.
Decision rule: if a narrow box fits your actual tools, prioritize the slim layout. If it does not, choose depth deliberately rather than assuming the tallest-looking box holds the most useful gear.
05 What “low profile” does—and does not—mean
A low-profile crossover generally places its lid lower relative to the bed rails to reduce obstruction of the rearward view. The box may still have a deep tub extending into the bed. The EC10842 addresses floor-space consumption through a slim body; the EC10802 prioritizes volume with a deeper body; the TBSD-72-A-LP adds an angled lower-tub geometry.
These distinctions matter more than a vague “low-profile” label. If your main objective is a tonneau that closes over a box, look for an explicitly documented compatible system instead of assuming any of these will work.
06 Frequently asked questions
Does low profile mean the toolbox fits under a tonneau cover?
No. Lid, hinge and cover-rail clearance must all be checked, and the lid must still be able to open.
Does a low-profile box reduce rear-window obstruction?
That is the intended design advantage, but actual sightlines depend on the truck, cab height, box placement and accessories.
Is the narrowest box always better for short beds?
Not if it cannot hold your equipment. Test the largest case you carry against the usable interior dimensions, not just the advertised outside size.
Can I use a low-profile box with a fifth-wheel hitch?
Only after checking the hitch and trailer clearance throughout the full turning range, including manufacturer requirements. Do not infer compatibility from the lid height.
Are low-profile boxes waterproof?
Seals can help resist moisture, but installation, lid condition and exposure matter. Do not assume any box is completely watertight.
Bottom line
Buy the layout that solves your real constraint: slim for retained bed floor, deep for larger tools, or angled where the bed shape calls for it. Low-profile styling is useful, but dimensions and opening clearance decide whether a box belongs on your truck.
