Blacked-out and light on its feet, the Weather Guard 364-5-02 is the 64" Hi-Side box for crews who want a murdered-out look without a payload penalty. Welded aluminum diamond plate under a tough black ARMOR TUF powder coat gives you 7.9ft³ in a slim 16" tall, 13-1/4" wide profile at a fraction of a steel box's weight. It fits a 6-1/2' or 8' bed with rail to spare, mounts high on one side rail with no drilling, and the black diamond plate hides grime while resisting road salt and corrosion.

What's Included:

364 Hi-Side aluminum diamond plate Hi-Side truck tool box, black
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
Removable parts bin
Full-perimeter weather seal with rain gutter, pre-installed
Weather Guard installation instructions

Features

Lightweight Aluminum Diamond Plate
The 364-5-02 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 7.9ft³ 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 364-5-02 opens to a clear 12-3/4" 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.

Fitment & Compatibility

Truck Class	Bed Length	Example Trucks	Fit
Full-size 6- standard	1/2', 8' (long bed)	F-150, Silverado/Sierra 1500 to 3500, Ram 1500 to 3500	✓ Yes, mounts on the bed side rail
Full-size 5-	1/2' (short bed)	-	● Verify clearance, the box may overhang a short bed
Mid-size and compact	-	Ranger, Colorado, Tacoma, Frontier, Maverick	✗ No, not designed for these trucks

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.

Installation

Type: Top-of-rail side mount, clamp-in with no drilling · Time: About 30 to 45 minutes · Tools: Socket or wrench set and a tape measure; no drill needed with the included under-rail brackets · Difficulty: Easy to moderate, best done with two people because of the 64" length and weight

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 64" long, 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 Door Replacement Walkthrough

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 364-5-02 fit my truck?

The 364-5-02 is 64-1/4" long and fits a full-size 6-1/2' standard or 8' long bed, leaving spare rail for a rack or second box. It mounts on either side rail. On a 5-1/2' short bed it may overhang, so measure first. 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 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 60 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?

You load the 7.9ft³ interior through two side doors, each with a 29" wide by 12-3/4" opening. Every door locks with a drill-resistant core and three-point latching, adjusts from 90 to 180 degrees, and pops off on tool-less QuickClips. The narrow 13-1/4", lightweight body makes this a fast, easy box to live with day to day.

Is it made in the USA and under warranty?

Yes. The 364-5-02 is made in the USA and backed by a Weather Guard Limited Lifetime Warranty against defects in materials and workmanship.

I really like having these on the work truck. It helps keep the inside of my cab clear of tools and work gear so I my passengers are more comfortable. They do not have full built-in shelves. At first I thought this would limit my organization. Now I like how many items I can fit in there that the shelves would be in the way. I would recommend this to someone who is looking to have better organization and likes to compartmentalize tasks. I want to label each door now 1-4 so that when I send someone to my truck they know where to go. These are pricey but worth it if you are trying to keep your pickup bed as functional as possible. Best part, lockable and dry inside. The handles are really easy to turn too. I want to put longer cables on my so the doors lay closer to the truck. Right now they are at head level and I am nervous I will hit my head. Also I want to use the doors as storage.
