THE CLAMP, REINVENTED.
We've over-engineered every aspect of the JackClamp. It'll withstand all the abuse you can throw at it and make your other clamps feel completely inadequate. They are.
The JackClamp can jack or hoist up to 300 lbs, clamp up to 32", spread gaps as small as 1/4", clamp irregular (even round) shapes and do it all without ever slipping.
