The Weather Guard 290-3-02 runs 90" down the rail to work a full 8' bed, yet keeps the slim 16" tall, 13-1/4" wide Hi-Side profile so it never blocks your mirrors or crowds the bed. That length turns into 11.1ft³ of locking storage riding up off the bed floor, with big 42-3/4" wide door openings that take full-length lumber, conduit and trim stock. It clamps to one side rail of an 8' long bed with no drilling. Heavy welded steel in a Brite White ARMOR TUF finish makes it the pry-resistant pick for crews who haul long material.

Two drill-resistant locking T-handle latches with three-point latching

Features
Heavy Welded Steel Body The 290-3-02 is built from heavy welded steel for the most rugged, pry-resistant Hi-Side box Weather Guard makes. It takes daily jobsite abuse and stands up to break-in attempts, so your tools stay put and protected shift after shift.
Brite White ARMOR TUF Finish A Brite White ARMOR TUF powder coat covers the smooth steel to fight scratches, fading and corrosion and give your truck a clean, professional white 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 11.1ft³ 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 290-3-02 opens to a clear 12-1/4" high by 42-3/4" 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 90-1/4" long, so it requires a full-size 8' long bed. 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.

Set the box on top of one bed side rail and position it front to back, then hook the included brackets under the rail lip and tighten the hardware evenly so the box sits flat and the doors seal. Because the box is 90" long and heavy steel, have a second person help lift and steady it while you clamp it down. Follow the Weather Guard Hi-Side and Super-Side installation instructions for exact bracket placement and torque.

Weather Guard's official step-by-step guide to pulling and replacing a box door, filmed on a high-side box. Weather Guard publishes it on this box's own product page, so keep it bookmarked in case a door ever needs to come off for service or gets damaged on the job.
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 290-3-02 fit my truck?
The 290-3-02 is 90-1/4" long and needs a full-size 8' long bed; it is too long for a 6-1/2' standard or 5-1/2' short bed. It mounts on top of either side rail. Measure your rail length and check cab clearance before ordering. It is not designed for mid-size or compact trucks.
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 90" box while you tighten the hardware.
Is this the steel box or the aluminum one?
This is the welded steel version, the most rugged and pry-resistant Hi-Side box Weather Guard offers. It weighs about 129 lb and is a great fit for contractors and fleets that want maximum durability. If you want to save weight, Weather Guard also builds this size in aluminum diamond plate.
What is the white finish like?
The steel body wears a Brite White ARMOR TUF powder coat that resists chips, fading and corrosion and keeps a clean, professional look. Wipe it down with mild soap and water to keep it bright.
How secure is it and how do the doors work?
The two side doors each open a generous 42-3/4" by 12-1/4" mouth into the 11.1ft³ interior, long enough to slide in full sticks of trim, conduit or molding. Each door uses a drill-resistant lock core with three-point latching, swings 90 to 180 degrees, and releases on tool-less QuickClips. The low 13-1/4" depth keeps the box slim while still holding a lot of long gear.
Is it made in the USA and under warranty?
Yes. The 290-3-02 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.
