Shop the range for vehicle underbody security.

Catloc systems protect catalytic converters and diesel particulate filters (DPFs) on vans, pickups, 4x4s and motorhomes. You use them to reduce theft risk by physically securing or shielding high-value exhaust components located under the vehicle.

These systems target a known weak point. Catalytic converter theft has increased because units contain valuable metals and are often easy to access from underneath.

Catloc kits are vehicle-specific and designed to mount using existing fixing points where possible. They secure or shield the exhaust section to make removal slower and harder.

Typical applications:

• Vans used for trade work
• Fleet vehicles
• Motorhomes and campervans
• Pickups and 4x4s with exposed exhaust systems

Key features:

• Vehicle-specific fitment kits
• Marine-grade stainless steel construction
• High-security fixings
• Underbody protection for CAT and DPF units
• Visual deterrent from below the vehicle

You select the correct Catloc based on vehicle make, model, engine type and exhaust layout. Fitment varies widely across manufacturers, so correct matching matters.

Garrison Catloc systems are used alongside van security upgrades such as deadlocks, slamlocks and shielding products for layered protection.
