"From $23K loss to not a single converter stolen"

"We had 34 catalytic converters in the span of 5 months which resulted in a loss of $23,440 + the time the vehicles were off duty. Since that time I decided to get CatClamp and we haven't had a single converter stolen."

George, fleet manager

"The city has not had a catalytic convertor stolen"

"As of August 2021, the city has not had a catalytic convertor stolen or even a known attempt to steal them on vehicles with an anti-theft device.... the thieves see these and realize it will take too long, so they move on."

Eric, maintenance superintendent

"Peace of mind once I had this installed"

"It worked! (...) last night, another thief made an attempt (caught on camera) and as soon as he went to look under and saw the cage, he drove off. I had peace of mind once I had this installed ... I highly recommend this product."
