Rock-solid install: Rigid mounting system that locks in place within minutes

Spencer Johnson

Style: Chevy/GMC

I am very pleased with this product; it is hefty which really shows its solid sheet metal construction and has a durable paint coating which should be resistant to chipping or fading. The use of ball bearing slides makes the drawer open smoothly. The lock feels tight and secure and holds the drawer well, it doesn’t rattle at all. The installation instructions are very easy to follow, and they provided everything to install except the wrench, haha. Also, a big shout out to it being manufactured in the USA.

Jerami Summers

Style: Chevy/GMC

Looks sharp, and no noise. This under-seat storage locker is a great way to keep my truck looking clean while storing my firearms. The other nice part, the 16-gauge steel construction is incredibly sturdy and there is absolutely zero rattle noise while driving through rough terrain. Easily accessible from the driver side, allows recovery of any property quick and easy. I highly recommend.

Side-Slide Access Design

Glide-open drawer for easy access- no need to lift your seat.

Top-Notch Security

Rugged, tamper-resistant locking system keeps your gear safe.

Vehicle-Specific Fit

Custom-fit for Ford, and Chevy/GMC crew cab pickups.
