Weather Guard 137 Aluminum Crossover Truck Tool Box, Mid-Size Deep, Bright Aluminum (137-0-04)

Give your work truck a classic, high-visibility look with the Weather Guard 137-0-04" bright aluminum diamond plate. Its clear ARMOR TUF powder coat lets the raw diamond plate shine through while sealing the aluminum against corrosion, fading and road salt. If you want the traditional, high-visibility look most buyers picture on a work truck, bright aluminum is the go-to choice. Scratches and swirl marks also tend to blend into the diamond plate instead of standing out. This compact, deep aluminum saddle box is sized for mid-size trucks and mounts across the bed rails behind the cab, adding depth for bulkier gear with 9.0ft³ of secured, weather-sealed storage. A five-piece welded aluminum diamond-plate body with a reinforced C-channel front keeps it strong yet light, and a full-perimeter D-shaped weather seal locks out rain and dust.

• Under-rail mounting clamps and hardware for a no-drill install

Features

Welded Aluminum Diamond-Plate Build
A five-piece welded aluminum diamond-plate body with a reinforced C-channel front panel keeps this box strong yet light. It resists jobsite abuse and road salt without adding the weight of a steel box. This one is finished in clear ARMOR TUF powder coat over bright aluminum diamond plate.

Bright Aluminum Clear ARMOR TUF Finish
A clear ARMOR TUF powder coat protects the raw aluminum diamond plate while keeping that bright, traditional work-truck look. It resists corrosion, road salt and fading without hiding the diamond-plate texture.

1Key UltraLock Security
Tamper-resistant push-button locks sit recessed when locked, giving a quick visual cue your gear is secured. The 1Key UltraLock system lets you code multiple boxes on a truck, or a whole fleet, to a single key.

Full-Perimeter Weather Seal
A memory-resistant D-shaped, multi-ridge weather strip runs the entire lid perimeter to keep rain, dust and debris off your tools, so your gear stays dry and ready in any weather.

Reinforced Lid With Gas Struts
Gas struts hold the reinforced lid open near 90 degrees for easy one-handed access, and welded strut shields protect them from damage. The steel-reinforced lid resists flex and stands up to daily use.

Saddle Fit Across The Bed
The box straddles the top bed rails behind the cab, keeping your bed floor open for sheet goods and cargo. Enhanced tie-down buckles and 12V PowerSync-ready access round out a box built for working trucks.

Reinforced Body, Automotive-Grade Hardware
Weather Guard specifies a five-piece welded body for the 137-0-04, with a C-channel reinforced front panel and a heavy-duty C-channel reinforced lid, so the box stays square when it is loaded and when someone stands on the lid. The latch is an automotive dual-stage rotary mechanism, the same style a truck door uses, so it pulls the lid down onto the seal instead of relying on a friction catch. A welded gas strut shield keeps loose tools from knocking the strut mount out of line. The D-shaped ribbed weather strip is memory resistant, so it springs back after years of closing rather than taking a set and letting water track in.

Installation

Type: Saddle mount across the top bed rails, clamp-in with no drilling  ·  Time: About 20 to 30 minutes  ·  Tools: Socket or wrench set and a tape measure; no drill needed with the included under-rail clamps  ·  Difficulty: Easy, best done with two people for the lift

Set the box across the two bed rails behind the cab and center it left to right. Hook the included clamps under each bed rail and tighten the hardware evenly so the box sits flat and the lid seals all the way around. Because the box is wide, have a second person help lift and hold it while you clamp it down. Follow the Weather Guard installation instructions for exact clamp placement and torque.
