This is the UWS crossover truck tool box, the box that sits across the bed just behind the cab. It holds 7ft³ in a 64" body with a low-profile lid that keeps it below the line of the bed rails for a clear rear view. It closes on two stainless steel paddle lock handles, set wide apart so they fall to hand from beside either bed rail. The tub is a single piece of 0.058" aluminum, the lid is UWS's patented RigidCore foam-filled design so it will not flex or bind, and a MicroSeal gasket runs the full perimeter of the opening to keep rain and dust out. The finish is matte black powder coat over diamond plate. This is the heavy-packaging version of the box: mechanically identical to the standard part, but crated for parcel carriage so it can ship without freight. UWS designs, fabricates and welds it in Florida and backs it with a limited lifetime warranty.

Features
Angled Body for Awkward Beds The angled ends let the box drop into beds whose wheel well shape or length will not take a straight-sided chest, which is what makes it worth looking at when a conventional box measures out just too long.
Extra-Thick 0.058" One-Piece Aluminum Tub The tub is formed from a single piece of 0.058" aluminum rather than welded up from thinner panels, so there are fewer seams to leak or split and the box keeps its shape when it is loaded with heavy hand tools, cordless kits and chain. Aluminum also means it will not rust out from the inside the way a painted steel box does once the coating is chipped, which matters on a box that lives outdoors and gets road salt thrown at it every winter.
Stainless Steel Lock Handles The lock handles are stainless steel, not plated pot metal, so they keep working after a few winters of salt and do not seize or bloom with rust. Both handles lock.
Connecting Rod for Either-Side Operation The two handles are tied together by an internal rod, so the box opens from the driver side or the passenger side without walking around the truck. On a wide bed that is the difference between grabbing a tool and climbing up into the bed to get it.
Enclosed Lock Rod The connecting rod runs inside an enclosure rather than exposed across the back of the tub. Loose cargo cannot fall against it and bend it, which is the usual reason a two-handle box eventually stops opening from one side.
Widespread Handles The handles are set wide apart toward the ends of the box so they fall to hand from beside the bed rail, instead of forcing you to lean across the bed to reach a center latch.
MicroSeal Weather Gasket A MicroSeal gasket runs the full perimeter of the opening and compresses as the lid closes, sealing out rain, road spray, dust and the fine grit that ruins bearings and fastener threads. It is the part of a tool box most owners only think about after they have found standing water inside a cheaper one.
Self-Opening Lid Release the paddle handles and the lid lifts and stays up on its own, close to a full 90 degrees. That is a genuinely useful detail when both hands are full or you are working in the dark: you are not holding a heavy lid open with a shoulder while you dig for a socket.
Fitment & Compatibility
Bed Type
Fit
Full-size pickup, standard bed width
✓ Yes, ideal application
Full-size pickup, 5.5' short bed
✓ Yes, a crossover box sits behind the cab and does not depend on bed length
Mid-size pickup (Tacoma, Ranger, Colorado)
● Usually yes, measure rail to rail first
Flareside, stepside and older narrow beds
● Measure rail to rail before ordering
Fit guidance: A crossover box spans the bed rails just behind the cab, so the measurement that matters is rail to rail, outside to outside, not bed length. This box is 64" across (UWS markets it as the 63" box; 64" is the true overall length), 20" front to back and 14.75" tall. The low-profile lid keeps it at or below the line of most bed rails for a clear rear view. Mounting hardware is included: 2 rail pads, 2 J-hooks, washers and nuts.

Set the box across the bed rails behind the cab, check the lid clears the rear window and any cab guard through its full travel, then clamp it down with the supplied hardware. Most crossover boxes clamp to the underside of the bed rail rather than bolting through, so no drilling of the truck is normally needed.

About UWS
UWS, United Welding Services, has been welding aluminum truck boxes in Florida since 1988. It is now part of the Lippert and CURT Group family, which is what gives a box at this price a real dealer network, real parts support and a warranty that means something years later. What has not changed is where the boxes are made: UWS designs, fabricates and welds them at its own plant rather than importing finished bodies, and that is visible in the details that cannot be fixed after the fact, such as square lids, consistent welds and gaskets that meet cleanly all the way around the opening.
Two UWS features do most of the work in this crossover truck tool box. The first is the patented RigidCore lid, filled with a solid foam core instead of left hollow, which is what stops a long lid flexing in the middle, drumming at speed or binding in its own opening as the box ages. The second is MicroSeal, a full-perimeter gasket that compresses as the lid closes and keeps out the rain, road spray and fine grit that ruin the contents of a cheaper box. Underneath both is a 0.058" one-piece aluminum tub, thicker than most of the competition and immune to the rust that eventually kills a painted steel box.
Prestige Truck is an authorized UWS dealer. Every box we ship is new, factory-packed, covered by the full UWS limited lifetime warranty and supported by UWS's US-based parts and service team.

RigidCore Strength Test: Tool Box Vs. Pickup Truck
UWS drives a pickup onto one of its RigidCore lids.
It is a marketing stunt and it is also the clearest demonstration of what the foam core actually does, which is stop a long lid flexing, denting or binding in its own opening. This box uses the same RigidCore lid.
MicroSeal Weather Test: Mud And A Pressure Washer
UWS buries a box in mud and then turns a pressure washer on it to show what the MicroSeal gasket keeps out.
Worth two minutes if you are deciding between this and a cheaper box with a plain foam strip, because sealing is the thing you only notice once it has failed.
How To Measure Your Truck Bed Before You Order
UWS walks through measuring a truck bed properly, which is the step that prevents almost every returned tool box.
Do this before you order: the measurement that matters for a box like this is the flat space or rail-to-rail width you actually have, not the advertised bed length.
Frequently Asked Questions
Straight answers on specs, fit and support
What are the actual dimensions, and will it fit my truck?
The box is 64" long, 20" deep and 14.75" tall overall, and it holds 7ft³. The usable tub inside measures 53" x 17" x 11.75". Measure your bed rail to rail, outside to outside, because a crossover box spans the rails rather than sitting in the bed.
Is the mounting hardware included?
Yes. UWS's parts list for this box is the box, 2 keys, 2 rail pads, 2 3" J-hooks, 2 1/4" washers and 2 1/4" nuts, which is everything needed to clamp it to the bed rails. Some models also include a divider tray. No drilling of the truck is normally required.
What is the difference between this and the standard UWS part?
Nothing about the box itself. UWS states that this part is identical to #TBS-63-A-LP-MB, with the only difference being that it is heavily packaged so it can travel by parcel carrier rather than by freight. You get the same box, the same warranty and, usually, a faster and cheaper delivery.
How well does it keep water out?
A MicroSeal gasket runs the full perimeter of the opening and compresses as the lid closes. No tool box is a submarine, and a box that is pressure washed straight at the seam or parked nose-down in standing water can still take some in, but in normal service it stays dry inside. Keep the gasket clean and it will keep sealing.
What is the finish, and how does it hold up?
Matte Black powder coat over aluminum diamond plate. Powder coat is far tougher than wet paint and, because the substrate underneath is aluminum, a chip does not start rust the way it would on a steel box. The matte finish is flat and non-reflective, so it hides marks better than gloss and suits a blacked-out truck. The finish carries a one-year warranty; the box itself is covered for a limited lifetime.
Does the lid stay open on its own?
Yes. Release the paddle handles and the RigidCore lid lifts and holds itself open at close to 90 degrees, so you have both hands free. The foam-filled lid is light enough for the mechanism to manage but stiff enough not to flex on the way up.

Look is great. 100 lbs
Look is great. 100 lbs lighter than my 2nd pick. Lid lock and opening are smooth. Only minor knock I give is the the tie down hooks are hard to install - thinking I should have done them before installing.

A must have
I really like this mat. I was apprehensive at first but, the mat does a great job of keeping things from sliding around without having to secure it. perfect fit. But i think i will be adding some short screws to secure the mat to the DECKED system.

I never knew how much I needed this
As with all BAK covers, the quality is amazing. What I didnt fully appreciate until installing was the ease of opening - especially in a lifted truck. No more need to find the right handhold. Just roll it back with a single hand. Its also great to see out of my rear window when fully open - something you lose with the fold back covers. Customer service is awesome. I has an installation question and the representative stayed on the line as I adjusted an alignment to ensure I did it properly.

Better then expected.
Searched for about 6 months to find the tonneau cover. I really wanted the security of a hard top without sticking above the bed rails it checked those boxes. I also did not want to drill my truck bed. The install was super simple my wife and I had it on the truck in about a half an hour.

The toolbox is nice. I
The toolbox is nice. I think Ill get a lot of years of service out of it. I like how the lid opens and the tie downs are a nice touch. It seems to be well built. And tough. Im pleased with my purchase and would buy another one.
