Industry reports say that the average catalytic converter thief needs nothing more than thirty seconds and a battery-powered saw blade to strip your vehicle of its converter. Usually containing palladium, platinum, and/or rhodium, a stolen catalytic converter can fetch thieves a pretty penny, not to mention cost you up to $1,000 in total repair costs to get it replaced. Protect yourself by neutralizing that saw and prolonging those precious seconds with the CatClamp Catalytic Converter Lock.

Airplane wire rope is the secret to the success of the CatClamp. Nearly unbreakable and impossible to saw with a standard handheld, this rope forms an impenetrable barrier around your catalytic converter. Not only does this rope attach your converter to your vehicle, but it also makes the CatClamp Catalytic Converter Lock surround the converter itself in a veritable forcefield of protection. Split-collar cage ends allow this herculean rope to pass through it as many as eight different times, and the collars on your Toyota 4Runner or Honda Element catalytic converter lock, or those for whatever vehicle you own, make sure everything stays in one place upon tightening.

Upgrading to the Cat Clamp MAXX lock gives you even more protection. In addition to everything you get with the standard Cat Clamp, you'll enjoy 100% stainless steel construction of both split-collars. Larger stainless ropes are even more difficult to cut through, and both permanent and temporary bolts are available to tighten, say, your Jeep's system to a Jeep Cherokee catalytic converter lock for the long haul. Best of all, each MAXX lock also includes a unique I.S.R. catalytic marking kit to give your Cat Clamp a permanent, traceable identity if (against all odds) a thief does somehow manage to break through this nearly unbeatable locking system.

Don't run the risk of having to foot the bill for an expensive catalytic converter replacement. Make sure thieves will skip your car with the made in the U.S.A. CatClamp Catalytic Converter Lock. Backed by a 1-Year Warranty for the standard Cat Clamp and a Lifetime Warranty for the MAXX.

The Catclamp instructions are pretty straightforward. You need to take some time to review exactly where and HOW you are going to run the cable in order to get best effectiveness of the system. On my application, due to it being a Class "C" motorhome, the only real option was the transmission crossmember in the front and the driveshaft pillow block support for the rear. This is for an E-series E450 motorhome chassis with the 6.8L V10 engine and 4-speed heavy-duty transmission. Be sure to lay the cable out to get the twisting bends out, and it goes pretty easy once the front and rear clamps with appropriate pipe diameter inserts are in place. Thread the cable through per instructions and then tighten everything down in stages for best clamping action. Excess cable can be routed to a point or clamped using c hardware cable clamp to attach it to an existing cable you just ran (my solution). Took about an hour crawling under the chassis to install it.

Cat converter was stolen from my Prius parked in front of the house. Decided this device is my best deterrent against repeat theft. My mechanic has installed these before, but first time on a Prius. He said it was no trouble to install. I don't hear any rattling. No photos of installation. In terms of price, ease of installation, and quality as a lock, I'm totally pleased.

Had two Catalytic converters stolen within two (2) weeks city of Chicago. got a CatClamp after second one and been safe for the last 18 months. Daughter bought a Jeep Wrangler and the converter is easy to get at, so put on a CatClamp so far so good, keeping foggers crossed. Second clamp was easier to install had a little experience.

Bought one for daughter's SUV after her converter was stolen twice in one month (Chicago)...YIKES!! So my other daughter who lives in the city just purchased a Jeep Wrangler I knew better than wait to see if it would happen to her. The SUV has not been touched in a year and the Jeep was new and just installed last week. Since this was the second one I put on it was easier but anyone with a little mech ability can do it. It looks intimidating and I'm sure 'would-be thieves' see it and just move on to the next victim. Cars with more road clearance seem to be the vehicle of choice.

I purchased the CatClamp online and it came the next day. I took it to the Honda dealer who was doing the work replacing my second stolen catalytic converter. When I searched the internet to find something to protect my catalytic converter, I didn't know such a device existed. When I found it, I was thrilled and immediately ordered it. The mechanic who installed it said that he had never heard of such a device. He was fascinated with installing it and even took pictures of it! So, I sure hope that this is the last catalytic converter that I'll ever need on my Honda Element!
