# Tuffy Underseat Lockbox 2/3 Length W/ Combo Lock For Chevrolet Silverado & Gmc Sierra

This high security welded steel security lockbox mounts under the rear 60 percent bench seat in your 2007-2018 Chevrolet/GMC 1500 or 2007-2019 Chevrolet/GMC 2500 HD/3500 HD Crew Cab truck. The three-fifths width formfitting design of the Tuffy lockbox has over 2100 cubic inches of lockable storage while leaving room for an aftermarket sub-woofer or other gear under the rear passenger side seat. Its secured contents are easily accessed by flipping the 60 percent rear bench seat up and lifting the lid. The unique design allows the space beneath the 60 percent bench seat to be used to stow firearms or other long items securely. This lock box comes standard with Tuffy's Pry-Guard Locking System and three-digit combination security locks with built in weather seals. Chamfered corners are incorporated into the design for easier passenger access and a more concealed form factor. The innovative mounting system is accessed from inside the box.

-   Crew Cab required. Does not fit Double and Regular Cab. No Drilling required. Fastens with original OEM hardware.
