Review on Enhanced Performance & Secure Latching: POWERTEC 20306 Toggle Clamp with Increased Capacity by Jarod Berthelson

They work great but if you want to use them for something that can move or push like a tailgate or something I made as a latch for a convertible camper van - you need to get the grinder onto the mounting plate to allow the lever to rotate a little more to ensure it doesn't bounce and open. otherwise they work perfectly.
