Keep your valuables out of sight and locked tight with the Tuffy Model 343 underseat storage box built exactly for Chevrolet Colorado and GMC Canyon Crew Cab trucks.

• BUILT FROM RUST-RESISTANT STEEL: Crafted from 16-gauge steel and finished with durable powder coating, this box fights dents, scratches, and corrosion when you haul damp gear day after day.
• SPACIOSLY HIDDEN DIMENSIONS: The 46-by-16-inch shape fits under your rear seat and cradles over 2,100 cubic inches of gear while leaving plenty of knee room behind.
• PRY-PROOF COMBO SECURITY: Use a private combo code or 10-tumbler keys to shut the heavy lid, which integrates with a Pry-Guard system designed to stop wedge-based break-ins.
• DRILL-FREE MOUNTING: The bracket system bolts straight to your manufacturer's original hole patterns using standard wrenches, getting you locked in without extra effort or mess.
• VERSATILE CAB FIT: Engineered for Colorado and Canyon Crew Cabs, the lockbox spans the full rear width and offers separate locking doors for single or double seat layouts.
• HEAVY-DUTY HOLD: At 35 pounds, the welded steel frame grips tight to your seat rails to stay steady during aggressive off-road runs or sudden highway stops.

Hide work manuals or electronic drives under your rear cushion, securing them with the combo lock before you step out of the truck.
