The Weather Guard 365-0-02 packs the volume of a bigger box into a 64" length by going wide. This Super-Side is 16-1/4" wide and 18" tall, so the same 64" that gives a Hi-Side 7.9ft³ gives it 10.8, all in lightweight welded aluminum diamond plate with a bright clear ARMOR TUF finish. You get the deeper, higher-capacity box without the weight of steel or the length of an 8' box, and it still fits a 6-1/2' or 8' bed and mounts high on one rail with no drilling.
Two side-opening doors with tool-less QuickClip hinges
Two drill-resistant locking T-handle latches with three-point latching
Under-rail mounting brackets and hardware for a no-drill install

Features
Lightweight Aluminum Diamond Plate The 365-0-02 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.
Clear ARMOR TUF Diamond Plate A clear ARMOR TUF powder coat covers the aluminum diamond plate to fight scratches, fading and corrosion and give your truck a classic bright 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 10.8ft³ 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 365-0-02 opens to a clear 14-3/4" high by 29" 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 64-1/4" 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 365-0-02 fit my truck?
The 365-0-02 is 64-1/4" long and fits a full-size 6-1/2' standard bed or 8' long bed. Because it is a taller, wider Super-Side, check side and cab clearance along with rail length. On a 5-1/2' short bed it may overhang. It mounts on either rail and 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 64" 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 65 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 bright aluminum finish like?
The aluminum diamond plate wears a clear ARMOR TUF coat that shows the bright tread pattern while sealing out corrosion. It cleans up fast and gives a classic, traditional work-truck look.
How secure is it and how do the doors work?
Two side doors each open a 29" wide by 14-3/4" tall mouth into the roomy 10.8ft³ interior, and the wide 16-1/4", 18" tall body takes cases and power tools a slim box will not. Each door has a drill-resistant lock core with three-point latching, opens 90 to 180 degrees, and pops off on tool-less QuickClips for full access.
Is it made in the USA and under warranty?
Yes. The 365-0-02 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.
