The UWS 34" trailer tongue box turns the dead triangle of space on the front of a trailer into 4.1ft³ of locking storage, which is where the straps, chains, binders and the spare tail light bulb should live rather than sliding around the deck. The V-shaped tub is cut to sit down onto the tongue and is compatible with most straight-tongue and A-frame trailers, including boat trailers. It is 34.75" long at the back, tapering to 20" at the point, 17" wide and 22" tall. The lid uses the patented RigidCore foam-filled core and self-opens, it locks with stainless steel paddle handles, and the tub has integrated tool organization moulded in. Finished in gloss black powder coat. Two keys are in the carton; U-bolts are not included.

UWS Trailer Tongue Tool Boxes
UWS's short film on the trailer tongue line, presented by professional monster truck driver Cynthia Gauthier, whose gear lives in one. It makes the case for the V-shaped tub that drops onto the tongue: extra-thick aluminum, heavy-duty locking hardware and a sealed lid, so straps, chains, binders and spare bulbs ride on the trailer instead of loose in the truck.
It runs 15 seconds and covers the line rather than this size, so check the tongue dimensions in the Specifications section against your trailer before ordering.
Features
V-Shaped Tub Made for the Tongue, 4.1ft³ The tub tapers from 33" at the back to 20" at the point, so it sits down onto the tongue rails instead of perching on top of them. That is what keeps the box low and stable and what makes the space usable at all.
Fits Most Straight-Tongue and A-Frame Trailers UWS designs this box for straight-tongue and A-frame trailers, boat trailers included. It is a universal fit rather than a trailer-specific kit, so the measurement that matters is your tongue geometry, not the brand of trailer.
Patented RigidCore Foam-Filled Lid The lid is foam-filled rather than hollow, so it resists bending and warping and keeps lining up with its latches. It self-opens and stays up, which matters when you are wrestling a chain out of it with wet gloves on.
Stainless Steel Paddle Lock Handles Stainless because this box gets rained on, salted and, on a boat trailer, submerged at the ramp. The handles are keyed and two keys are included.
Integrated Tool Organization The tub has organization moulded in rather than being a bare box, so small items are not left rolling loose under a coil of chain.
Designed, Fabricated and Welded in Florida UWS builds this box in its own Florida plant and backs it with a limited lifetime warranty on workmanship and materials, one year on the finish and one year on parts.

✓ Yes
Boat trailers
✓ Yes, UWS lists boat trailers specifically

Fit guidance: This is a universal-fit box rather than a trailer-specific kit, so measure your tongue before ordering. The box is 34.75" long at the back, narrows to 20" at the point and is 17" wide and 22" tall. The V has to sit down over your tongue rails, so check the angle of your A-frame as well as the length available between the coupler and the trailer deck. Leave the jack, the coupler handle and the safety chains free to operate. Hardware is not included; UWS recommends at least two square 3/8" U-bolts with nuts and washers.

Mounting hardware is not included, because tongue sizes vary too much for one kit to fit. UWS recommends a minimum of two square 3/8" U-bolts with nuts and washers, sized to your tongue rail. Set the box on the tongue, check the coupler, the jack and the safety chains all still operate freely, then drill from the underside so any burr is on the outside of the box. UWS is explicit that a tool box is not a place for flammables or hazardous material, so no fuel cans, solvents, propane or cutting torches. Never load past the vehicle manufacturer's rated capacity.

About UWS
UWS is short for United Welding Services, and the name is the point. The aluminum boxes in this line are designed, fabricated and welded in Florida rather than assembled from imported panels, and the tub is formed from one piece of extra-thick aluminum so there is no seam along the floor of the box for water to work its way into. UWS is part of the CURT Group, a Lippert company, which is what puts a national warranty and a real replacement-parts program behind a box that is still built in a single plant. Handles, gas struts, lid gaskets, striker brackets and keys are all cataloged parts you can buy years later, which is the practical difference between a box you repair and a box you replace.
A tongue box lives a harder life than a truck box. It sits ahead of the trailer wheels where it catches everything the tow vehicle throws back at it, it gets loaded with wet chain and muddy straps, and on a boat trailer it gets dunked in the ramp more often than anyone admits. Aluminum is the right material for all three. The full-height tub gives you room for a full chain and binder set rather than just straps. UWS backs it with a limited lifetime warranty on workmanship and materials.
Prestige Truck is an authorized UWS dealer. Every box we ship is new and in the factory carton, covered by the full UWS factory warranty, and backed by the UWS replacement-parts program if a handle, strut, gasket or key ever needs renewing.

Model
This OneUWS 34" Trailer Tongue Box, Gloss Black Aluminum (TBV-34-BLK)
It fits most straight-tongue and A-frame trailers, but it is a universal box, so measure first. You need 34.75" of tongue length available, 17" of width, and an A-frame angle the V can sit down into. Check the coupler, the jack handle and the safety chains all still work freely with the box in place.
What hardware do I need?
None comes in the carton, because tongue rails vary too much. UWS recommends a minimum of two square 3/8" U-bolts with nuts and washers, sized to your tongue. Drill from the underside so the burr ends up outside the box rather than inside it.
Can I use it on a boat trailer?
Yes, UWS lists boat trailers specifically. It is a sensible choice there because the box is aluminum and the handles are stainless, so a dunking at the ramp is not the problem it would be with a steel box.
How much does it actually hold?
4.1ft³, which is enough for a full chain and binder set, straps, a wheel chock and the spares you want to keep dry. The tub tapers with the tongue, so the usable space is at the wide back end.
Is it lockable?
Yes, stainless steel paddle handles with keyed locks, and two keys are included. Stainless is the right choice on a trailer that gets rained on and salted, and it is why the handles still work in year five.
What does the warranty cover?
A limited lifetime warranty on workmanship and materials, one year on the finish and one year on parts. Handles, struts, gaskets and keys are cataloged UWS service parts if you need one later.

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.
