Weather Guard 124 Aluminum Gull-Wing Truck Tool Box, Full-Size Standard, Gloss Black (124-5-04)

Blacked-out and built to work, the Weather Guard 124-5-04 wears a deep gloss black ARMOR TUF powder coat that matches modern dark trim and wheels. The wet-look shine wipes clean easily and stands up to sun, salt and jobsite abuse. Pair it with black wheels and dark trim for a clean, factory-blacked-out build that still shrugs off the weather. The deep, even shine photographs well too, which is a plus if you show or resell the truck. This full-size, standard-width gull-wing crossover box mounts across the bed rails behind the cab and opens from either side through two independent lids, giving you 11.3ft³ 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.

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 gloss black ARMOR TUF powder coat.

Gloss Black ARMOR TUF Finish
A deep gloss black ARMOR TUF powder coat gives the box a sleek, wet-look shine that pairs with blacked-out trim. The tough coating resists scratches, fading and corrosion so it keeps its finish for years.

Dual-Stage Rotary Latch, 1Key Compatible
Each gull-wing lid uses an automotive-grade dual-stage rotary latch for smooth one-touch closing and solid break-in resistance, and the box is 1Key UltraLock compatible so you can key it into the same one-key system as your other Weather Guard boxes.

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.

Dual-Lid Gull-Wing Access
Two independent gull-wing lids open from either side of the truck, so you can reach tools from whichever side you are standing on without walking around the bed. Each lid operates and locks on its own.

Crossover Fit With Bed Clearance
The box suspends across the bed rails behind the cab and leaves room underneath, and a 12V access port supports lights and electrical add-ons. A removable divider tray helps organize smaller tools and hardware.

Reinforced Body, Automotive-Grade Hardware
Weather Guard specifies a five-piece welded body for the 124-5-04, 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 gull-wing box across the two bed rails behind the cab and center it left to right, then hook the included clamps under each bed rail and tighten the hardware evenly so the box sits flat and both lids seal. Because the box is wide and opens from both sides, 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.
