Portable Quick Vise

Designed for one-handed operation, this vise has a release trigger that disengages the movable jaw so you can slide it quickly into position; for final tightening, depressing the main handle drives a ratcheting cam mechanism, advancing the jaw incrementally to apply up to 300 lb of clamping force. The jaw faces are canted inward slightly so the tops touch first as they close. As they tighten, the jaws become parallel, distributing force evenly for a secure hold.
