Weather Guard 372 Hi-Side Truck Tool Box, 72 in Black Aluminum (372-5-02)

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.

What's Included:

• 372 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 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.

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 72" 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 72" 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.
