Features

Below-Bed-Rail Fit
The 634-5-04 sits below your truck bed rail, so it preserves rear-window visibility and clears tonneau covers, lids and truck caps. You keep a tidy bed profile and still get 10.0ft³ of lockable storage.

90 Degree Zero-Clearance Cover
The cover opens a full 90 degrees for easy, wide-open access, and the offset zero-clearance design lets the back of the chest sit tight against the front of the bed so you do not lose usable bed length.

1Key UltraLock Compatible Security
An automotive-grade lock and latch system resists prying and tampering, and the chest is 1Key UltraLock compatible, so you can code it and every other 1Key box on your truck or fleet to a single key.

Full Weather Seal
A full perimeter weather seal keeps rain, snow and dust out, so your tools and gear stay dry and ready in wet weather and on dusty jobsites.

12V Access Port and Tie-Downs
A 12-volt access port makes electrical up-fits simple, and reinforced tie-down buckles give you enhanced attachment points for multiple strap configurations to secure the chest and lash down cargo.

Aluminum Build, Gloss Black ARMOR TUF Finish
The 634-5-04 is built from aluminum diamond plate and finished in Gloss Black ARMOR TUF powder coat, which resists corrosion, scuffs and fading for years of dependable, professional-looking service. Made in the USA.

Set the chest in the bed against the front wall so the offset back sits flush and the cover clears the bed rail. Secure it with tie-down straps through the reinforced buckles or with bolt-down hardware per the Weather Guard instructions, then confirm the cover opens a full 90 degrees and the weather seal closes all the way around. Because the chest is wide, have a second person help lift it into place.

How the 1Key UltraLock System Works

A step-by-step look from Weather Guard at what the 1Key UltraLock actually does: how the cylinder accepts a new code, why the red push button retracts when the box is locked, and how the latch pulls the lid down against the seal. Worth two minutes before you set the box up.

How to Code Your 1Key UltraLock Lock

Weather Guard's official walkthrough for coding the lock so this box opens with the same key as the rest of your Weather Guard boxes. Follow it once when the box arrives and you can stop carrying a separate key for every lid on the truck.

Protect Your Gear and Your Reputation

Weather Guard's own film on why a working truck earns its keep from what is bolted to it. It frames the boxes, racks and bed equipment as the difference between arriving ready and arriving short, which is the thing a customer actually notices. It is a short manufacturer-made overview rather than a product demo, so watch it for the why rather than the how. If you are outfitting a truck from scratch it is a useful place to start before you pick individual part numbers.

Frequently Asked Questions

Straight answers on specs, fit and support

Why does it sit below the bed rail?

The 634-5-04 is designed to sit below your truck bed rail so it preserves rear-window visibility and clears tonneau covers, lids and truck caps. The offset zero-clearance cover still opens a full 90 degrees even with the chest pushed tight against the front of the bed.

How secure is it, and can it share a key with my other boxes?

It uses an automotive-grade lock and latch system that resists prying and tampering, and it is 1Key UltraLock compatible, so you can code it and every other 1Key box on your truck or fleet to a single key.

Will it keep my tools dry?

Yes. A full perimeter weather seal runs around the cover to keep rain, snow and dust out, so your gear stays dry and ready in wet weather and on dusty jobsites.

Will it fit my truck?

The 634-5-04 is about 58" long by 20" wide by 19" tall, a full-size chest for full-size beds. It sits below the bed rail against the front of the bed. Confirm your bed floor length and cap or tonneau clearance before ordering.

Can I run power to it or strap it down?

Yes. A 12-volt access port makes electrical up-fits easy, and reinforced tie-down buckles give you enhanced attachment points for multiple strap configurations to secure the chest and lash down cargo.

What is it made of and is it under warranty?

It is built from aluminum diamond plate with a Gloss Black ARMOR TUF powder-coat finish, made in the USA, and backed by a Weather Guard Limited Lifetime Warranty against defects in materials and workmanship.
