Keep tools locked down and off the bed floor with the Weather Guard 175-3-04 lo-side truck tool box. This 56" box wears a clean white ARMOR TUF finish over welded steel. White is the fleet standard, easy to spot in a crowded yard, and it reflects the sun so the steel and your tools stay cooler than a dark box. It mounts on top of one bed side rail so it rides low, preserves your rear visibility and leaves the bed floor open for sheet goods and cargo, and it locks down 4.0ft³ of weather-sealed storage behind the tamper-resistant 1Key UltraLock push-button lock.

Features
56" of Secure Side-Rail Storage At 56" long the 175-3-04 runs along one bed side rail and gives you 4.0ft³ of lockable, organized storage while keeping the rest of the bed floor clear. It carries a full day of hand and power tools without taking over the bed.
White Steel Finish A White ARMOR TUF powder coat seals the welded steel body against rust and chips and keeps a clean, professional look that is easy to spot in a busy fleet yard. White also reflects heat, so tools inside stay a little cooler in the sun.
Fleet-Ready White White is the classic fleet and municipal color, so it is easy to number, decal and spot across a busy jobsite. It also reflects heat, which helps keep the steel box and its contents cooler in direct sun.
Full-Perimeter Weather Seal A memory-resistant, multi-ridge weather strip runs the entire lid perimeter to keep rain, dust and debris out, and a drain plug lets any moisture that does get in escape, so your tools stay dry and ready on wet and dusty jobsites.
1Key UltraLock Security A tamper-resistant lock pairs a keyed cylinder with a recessed red push-button that sits flush when locked, giving you a quick visual cue your gear is secured. The 1Key system lets you code multiple boxes on a truck or a whole fleet to one key.
Organized With a Removable Tray A removable tray rides up top for fasteners and hand tools while longer items stow below, so your kit stays sorted instead of sliding around the box. It lifts out when you need the full depth for bigger gear.
Reinforced Body, Automotive-Grade Hardware Weather Guard specifies a heavy-duty welded body for the 175-3-04, with a C-channel reinforced front panel and a heavy-duty C-channel reinforced lid, so the box stays square when it is loaded and when someone stands on the lid. The latch is an automotive dual-stage rotary mechanism, the same style a truck door uses, so it pulls the lid down onto the seal instead of relying on a friction catch. A welded gas strut shield keeps loose tools from knocking the strut mount out of line. The D-shaped ribbed weather strip is memory resistant, so it springs back after years of closing rather than taking a set and letting water track in.

Fit guidance: Lo-Side boxes mount on top of one bed side rail, so they keep the bed floor open and leave the rest of the bed clear for cargo. At 56" long this box fits most full-size 6'6" and 8' beds with room to spare, fits many full-size 5'6" short beds, and fits a lot of mid-size trucks. It mounts on either the driver or passenger side rail. Always measure your usable bed side rail length and confirm clearance behind the cab before ordering.

A step-by-step look from Weather Guard at what the 1Key UltraLock actually does: how the cylinder accepts a new code, why the red push button retracts when the box is locked, and how the latch pulls the lid down against the seal. Worth two minutes before you set the box up.
How to Code Your 1Key UltraLock Lock
Weather Guard's official walkthrough for coding the lock so this box opens with the same key as the rest of your Weather Guard boxes. Follow it once when the box arrives and you can stop carrying a separate key for every lid on the truck.
Protect Your Gear and Your Reputation
Weather Guard's own film on why a working truck earns its keep from what is bolted to it. It frames the boxes, racks and bed equipment as the difference between arriving ready and arriving short, which is the thing a customer actually notices.
It is a short manufacturer-made overview rather than a product demo, so watch it for the why rather than the how. If you are outfitting a truck from scratch it is a useful place to start before you pick individual part numbers.
Frequently Asked Questions
Straight answers on specs, fit and support
What bed size do I need for the 175-3-04?
This box is 56" long and mounts on one bed side rail, so it fits most full-size 6'6" and 8' beds easily, fits many 5'6" short beds, and fits a lot of mid-size trucks. Measure your usable side rail length and confirm clearance behind the cab before ordering.
What is the finish on the 175-3-04?
It is welded steel finished in White ARMOR TUF powder coat, the fleet-ready choice. The powder coat resists rust and chips, keeps a clean professional look, and white reflects heat so contents stay cooler in the sun.
Why choose the white steel box?
White is the fleet-ready choice, easy to decal and identify across a crew of trucks, and it reflects heat so contents stay cooler in the sun. The steel body also adds strength and heft for demanding fleet use.
How big is it, and is it covered by a warranty?
The exterior measures about 56"L x 17"W x 13"H with 4.0ft³ of storage, and it weighs about 79.5 lb. It is built from welded steel in white, and it is made in the USA and backed by a Weather Guard Limited Lifetime Warranty against defects in materials and workmanship.
How does it lock?
It uses the Weather Guard 1Key UltraLock, a tamper-resistant design that pairs a keyed cylinder with a recessed red push-button that sits flush when locked. The 1Key system also lets you code multiple boxes on a truck or an entire fleet to a single key.
Can I run electrical accessories with it?
Yes. The box includes 12V access for electrical upfits, so you can wire in lights or other accessories, and enhanced tie-down buckles give you extra clearance for straps on the lid.

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.
