Our Solution

Catloc is the global leading brand of catalytic converter theft prevention solutions, with the number of products installed in excess of 40,000 vehicles each year both within the UK and abroad.

Our range of products have been specifically designed to address the theft of a vehicle’s catalytic converter or exhaust system. With over 45 bespoke fitments, each design has carefully considered how to offer the best protection to deter a thief.

We design, develop and distribute the largest range of bespoke products to protect catalytic converters and exhaust systems. Always focused on developing innovative, effective and economical solutions, multiple vehicle manufacturers have tested and approved products from the Catloc range, promoting these to their customers as the best line of defence against exhaust system theft.


All products are manufactured using marine grade stainless steel for strength and durability, supplied with high security anti-tamper fixings, fully illustrated instructions and our Catloc ISR security marking and registration system.

Depending on the vehicle it is being fitted to, a chain attachment is also used.  Our chain is manufactured to the same high standards as insurance approved motorcycle chains and as a further theft deterrent, always sleeved in a high visibility green silicone.

All products offer maximum protection, aligned with ease of fitment by using specific fixing points on the vehicle.
