The Weather Guard 372-5-02 spans six feet of bed rail in a slim, blacked-out package. Its 72" aluminum diamond-plate body stands only 16" tall and 13-1/4" wide, holds 8.9ft³, and a tough black ARMOR TUF coat gives it a murdered-out look that hides grime. The wide 33" doors load long levels and trim, the lightweight build spares payload versus steel, and it mounts high on one rail of a 6-1/2' or 8' bed with no drilling.

Features
Lightweight Aluminum Diamond Plate The 372-5-02 is formed from welded aluminum diamond plate, so it adds locking storage without the weight penalty of steel. Aluminum naturally resists rust and corrosion, which keeps the box working and looking good through road salt and wet weather.
Black ARMOR TUF Finish A black ARMOR TUF powder coat covers the aluminum diamond plate to fight scratches, fading and corrosion and give your truck a blacked-out diamond-plate look. ARMOR TUF is Weather Guard's toughest coating, built to hold up to sun, chemicals and the weather.
Twin Locking Doors, Drill-Resistant Locks Two side-opening doors each use a drill-resistant lock core and a three-point latching system to resist break-ins, so gear on both ends of the box stays secure. The doors open wide for easy reach into the full 8.9ft³ interior.
Tool-Less QuickClip Doors The doors adjust from 90 to 180 degrees and pop off with QuickClips, no tools required, so you can fully remove a door for loading and clip it back on in seconds. It makes packing long or bulky gear far easier.
Rain Gutter and Full Weather Seal A rain gutter design paired with a full-perimeter weather seal keeps rain, dust and debris out of the box and off your tools. Your gear stays dry and ready in wet weather and on dusty jobsites.
Rides High, Frees Your Bed Floor The Hi-Side design mounts on top of one bed side rail and stands up along the bedside, so your tools ride up and out of the way and the bed floor stays open for sheet goods, lumber and cargo. A removable parts bin keeps small items organized up top.
Removable Parts Bin and a Wide Door Opening Each door on the 372-5-02 opens to a clear 12-3/4" high by 33" wide opening, which is enough to slide long hand tools and cases straight in from the side of the bed. A removable parts bin rides inside for fasteners, fittings and the small parts that otherwise end up loose in the bottom, and it lifts out when you need the full length of the box.

Fit guidance: Hi-Side and Super-Side boxes mount on top of one bed side rail and stand up along the bedside, so the box rides above the wheel well and keeps the bed floor open. This box is 72-1/4" long, so it fits full-size 6-1/2' standard and 8' long beds. It can mount on the driver or passenger side rail. Always measure your bed rail length and check cab and bedside clearance before ordering, and note it is not designed for mid-size or compact trucks.

Weather Guard Truck Box Lineup and 1Key UltraLock
This official Weather Guard overview tours the current truck box lineup and the 1Key UltraLock security system that runs across it. You see how one coded key can open every Weather Guard box on the truck, from saddle to lo-side to hi-side, with a pop-up red button that tells you at a glance whether a box is locked. It highlights the sloped, reinforced lids and the ARMOR TUF powder coat that let these boxes shrug off weather and jobsite abuse. If you run more than one box, or a whole fleet, it shows why keying everything alike saves time every day.
Best Upgrade for Your Truck
This is Weather Guard's own brand film about outfitting a working pickup, built on the idea that the truck should already be loaded and organized before the day starts. It puts the bed and rail equipment in the context of a real work day rather than a spec sheet.
Watch it if you are still deciding how much storage a truck actually needs. It is the clearest short look at how Weather Guard boxes, racks and drawer units are meant to work together on one vehicle, and it comes straight from the manufacturer rather than a reseller.
Frequently Asked Questions
Straight answers on specs, fit and support
Will the 372-5-02 fit my truck?
The 372-5-02 is 72-1/4" long and fits a full-size 6-1/2' standard or 8' long bed, sitting low at 16" tall. It will overhang a 5-1/2' short bed, so measure your rail first. It mounts on either side rail and is not designed for mid-size or compact pickups.
Does it require drilling to install?
No. The box ships with under-rail brackets and hardware, so it clamps to the top of your bed side rail without drilling. Most installs take about 30 to 45 minutes and go easiest with two people to lift and hold the 72" box while you tighten the hardware.
How much does it weigh and is it strong?
It is built from welded aluminum diamond plate and weighs only about 64 lb shipping, far lighter than a comparable steel box, which saves payload and makes it easier to mount. Aluminum also naturally resists rust, so it holds up to road salt and wet weather while staying secure with drill-resistant locks.
What is the black finish like?
The aluminum diamond plate wears a glossy black ARMOR TUF powder coat for a rugged, blacked-out look, and the aluminum resists corrosion underneath. It hides grime a bit better than a bright finish and cleans up with mild soap and water.
How secure is it and how do the doors work?
Each side door opens a wide 33" by 12-3/4" mouth into the 8.9ft³ interior for long, thin material. The doors lock with a drill-resistant core and three-point latching, swing 90 to 180 degrees, and pop off on tool-less QuickClips. The slim 13-1/4" body keeps the profile low and the weight down.
Is it made in the USA and under warranty?
Yes. The 372-5-02 is made in the USA and backed by a Weather Guard Limited Lifetime Warranty against defects in materials and workmanship.

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.
