Features
- Top security protection: Weather Guard pairs an automotive-grade lock with dual-stage rotary latches, a setup it says guards against picking.
- 1Key UltraLock: Code the lock to its own key or to one key shared by every 1Key UltraLock box on your truck or across your fleet.
- Push-button lock: The red push-button drops back into the lid once locked, so you can tell at a glance that the box is secured.
- Full weather seal: A ribbed, D-shaped strip that resists taking a set seals the lid against rain, wash water and dust.
- Enhanced tie-down buckles: The buckles leave extra room, so several straps can hook on when you secure a load beside the box.
- ARMOR TUF finish: Gloss black ARMOR TUF powder coat protects the aluminum and, Weather Guard says, keeps the box looking new for years.

Frequently Asked Questions
Will it fit my Silverado 1500?
It is on our fitment list for that truck. Wheel wells differ by bed, so measure the space over yours before ordering.
Can I put it on the driver side?
No. It is built for the passenger side. The 172-5-04 is the matching box for the other side.
Do I have to drill my truck?
Yes. Weather Guard's sheet for the 172-X-04 and 173-X-04 sets blind fasteners in drilled holes, using 3/16", 3/8" and 1/2" bits. Make sure each hole is deep enough for the fastener before you set it.
What about an aluminum truck bed?
Coat every drilled hole with zinc-rich primer, then fit plastic washers above and below each blind fastener, as Weather Guard's sheet describes.
Driver side or passenger side?
Each box is built for one side: the 172-5-04 goes on the driver side and the 173-5-04 on the passenger side. Order both for a matched pair.
How do I lock it?
Turn the key counterclockwise to lock; the button then stays pressed in until you unlock it. Turn the key clockwise and the button pops out, ready to release the latches.
Installation
Here's the short version. Follow Weather Guard's install sheet (below) for the exact positions and hardware.
- Set the box in place with the cover open, flat on the floor and about 1" from the bed rail; check the tailgate closes. Fasten to the bed floor, not a liner or mat.
- Hold the end mounting angle against the box with its foot on the stake pocket or inner wall, mark and center punch one hole on each.
- Drill both 3/16", open the box hole to 3/8" and the stake-pocket hole to 1/2", set the blind fastener and bolt on the angle.
- Fit the floor mounting angle (spacer if needed) or the lower mounting angle as shown.
- If the box can rest on the wheel well, drill 3/16" then 3/8" through box bottom and wheel well top and bolt through instead.
- Check each hole is deep enough before setting a blind fastener; on aluminum beds follow the upfit steps on p2.
