Weather Guard 164 Lo-Side Truck Tool Box, 87" Textured Matte Black Aluminum Diamond Plate (164-52-04)

Keep tools locked down and off the bed floor with the Weather Guard 164-52-04 lo-side truck tool box. This 87" box wears a textured matte black ARMOR TUF finish over aluminum diamond plate. The textured matte coat is the choice when you want a stealthy, no-shine look that stays low-key even after the box picks up jobsite dust. It mounts on top of one bed side rail so it rides low, preserves your rear visibility and leaves the bed floor open for sheet goods and cargo, and it locks down 7.0ft³ of weather-sealed storage behind the tamper-resistant 1Key UltraLock push-button lock. Aluminum keeps it lighter than a comparable steel box, so it will not eat into your payload.

What's Included:

• 164 Series 87" Lo-Side aluminum truck tool box in textured matte black
• 1Key UltraLock keyed cylinder with recessed red push-button latch
• Under-rail mounting clamps and hardware for a no-drill install
• Gas strut for controlled lid lift
• Removable tray
• Full-perimeter weather seal, pre-installed
• Drain plug
• Weather Guard installation instructions

Features

87" of Secure Side-Rail Storage
At 87" long the 164-52-04 runs along one bed side rail and gives you 7.0ft³ of lockable, organized storage while keeping the rest of the bed floor clear. It swallows long levels, pipe and power tools that will not fit a shorter box.

Textured Matte Black Diamond Plate Finish
A Textured Matte Black ARMOR TUF powder coat covers the aluminum diamond plate and knocks down glare, so the box hides dust, fingerprints and light scratches far better than a glossy finish. The result is a stealthy, modern look that stays sharp.

Stealth Look That Stays Clean
Textured matte black is the stealth choice, and unlike gloss it does not throw glare or broadcast every fingerprint and fine scratch. It keeps a purposeful, tactical look on blacked-out and off-road builds even after a hard day.

Enhanced Tie-Downs and 12V Access
Enhanced tie-down buckles give extra clearance for universal or multiple straps so you can lash cargo down on the lid, and a 12V access point supports electrical upfits when you add them.

1Key UltraLock Security
A tamper-resistant lock pairs a keyed cylinder with a recessed red push-button that sits flush when locked, giving you a quick visual cue your gear is secured. The 1Key system lets you code multiple boxes on a truck or a whole fleet to one key.

Lightweight Welded Aluminum Build
The 164-52-04 is built from welded aluminum diamond plate, so it resists corrosion and dents while staying lighter than a comparable steel box. It is made in the USA and backed by a Weather Guard Limited Lifetime Warranty against defects.

Reinforced Body, Automotive-Grade Hardware
Weather Guard specifies a heavy-duty welded body for the 164-52-04, 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: Side-rail mount, 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 because of the length

Set the box on top of one bed side rail and position it front to back, then hook the included clamps under the rail lip and tighten the hardware evenly so the box sits flat and the lid seals. Because the box is long, have a second person help lift and steady it while you clamp it down. Follow the Weather Guard installation instructions for exact clamp placement and torque.
