Weather Guard 120 Steel Crossover Truck Tool Box, Full-Size Low-Profile, Gloss Black (120-5-04)

Blacked-out and built to work, the Weather Guard 120-5-04 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, low-profile steel saddle box mounts across the bed rails behind the cab and keeps a lower lid height for better rear visibility, with 11.0ft³ of weather-sealed storage. A heavy-duty formed steel body with a reinforced lid stands up to jobsite abuse, and a full-perimeter D-shaped weather seal locks out rain and dust.

• 120 Series full-size low-profile steel crossover (saddle) tool box in gloss black

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

Features

Heavy-Duty Steel Build
A heavy-duty formed steel body with a reinforced lid and front panel stands up to years of loading, weather and road abuse. Steel gives this box maximum strength and a solid, secure feel. 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.

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 120-5-04, 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 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.
