About The Catlock®

The Catlock® is strong, simple and versatile.


Its steel plates adjust to the various-sized catalytic converters of nearly every make and model of at-risk vehicle (trucks, SUVs and vans) in the U.S., particularly the universal catalytic converters often used to replace the original factory catalytic converter after a theft.

Every component of The Catlock® consists of high-grade steel, including the aircraft-quality cable used to secure the catalytic converter to the vehicle’s frame. Each hardware component has been carefully thought out to ensure the quick and proper installation of The Catlock®. Installation requires only a wrench and screwdriver and much of the assembly is done by hand without having to be under your car.

Although The Catlock® is rugged; it’s actually quite light, weighing just 4 pounds.
It ships quickly in a small, convenient package.

About Monat Technologies

Monat Technologies is a Phoenix, Arizona-based LLC established in 2008 by Ian Monat and Steven Meislahn. After the catalytic converter was stolen from Ian’s Toyota 4Runner, he set out to help others victimized by catalytic converter theft, by creating an effective and easy-to-install catalytic converter anti-theft device sold at an affordable price.

However, Ian’s professional background lies in sales and marketing and the skills of a mechanical engineer were needed to create The Catlock®. With the help of the Technology Ventures Services Group (TVSG) and Sun Devil Entrepreneurship Network (SDEN) at Arizona State University, Ian met Steven, a talented mechanical engineer, and Monat Technologies was formed.

The Catlock® underwent dozens of design iterations and months of strenuous product testing before its current design was chosen for its simplicity and versatility. All the while, Monat Technologies partnered with the TVSG for assistance with market, financial, and legal matters and engaged Phoenix-based suppliers to bring The Catlock® from vision to reality. We are excited to offer you The Catlock® and we hope you’ll gain peace of mind knowing your catalytic converter is under your vehicle and not in the hands of thieves.
