Product details
The Tuffy lockbox mounts under the rear seat in Chevy and GMC Crew Cab and Double Cab pickup trucks. This high security welded steel security lockbox has a full width formfitting design creating over 3500 cubic inches of lockable storage. Easily access your secured contents by flipping up the corresponding lid under your 60/40 split bench seat. The unique design allows the full width to be used to stow firearms or other long items. Feel confident securing your gear using Tuffy's Pry-Guard Locking System with a 10 tumbler double bitted security lock with built in weather seals. Mounts inconspicuously under the seat out of sight of opportunistic thieves with chamfered corners for easier passenger access. Declutter your space by quickly and easily installing this Tuffy lockbox using the factory hardware without drilling. When you need additional floor space, simply remove the lockbox in seconds without the need for any tools.
