Description
Secure Storage Solution. The Tuffy Security Products Underseat Lockbox with Combo Lock offers a high-security storage option concealed under the rear seats of compatible trucks. It provides a locked compartment designed for safely storing firearms, tools, or valuables, accessible by flipping up the lid of the 60/40 split seat. This lockbox helps keep contents protected from theft while maximizing usable interior space.
Construction and Appearance. Manufactured from heavy-duty welded steel, the lockbox features a durable textured powder coat finish in black for resistance against wear and corrosion. The design incorporates a weather-resistant lid with a unique hinge system and pin-lock hinge for added security and longevity. Chamfered corners ensure ease of access without compromising a stealthy appearance under the seat.
Installation. Designed for straightforward installation, this lockbox mounts using factory OEM hardware with no drilling required. The installation process is quick and accessible, and the lockbox can be removed rapidly from inside when unlocked, eliminating the need for tools.
Application. This lockbox is specifically fitted for 2020 to 2026 Sierra 3500 HD Double Cab and Crew Cab models. It does not fit other cab configurations or unrelated vehicle models due to the precise underseat mounting design catering only to these specific truck bodies.
