The IRWIN Original™ Locking Chain Clamp's chain holds and locks around any shape or size, so it's ideal for awkward shape pieces.

You just have to turn a screw to adjust pressure and fit work, and it stays adjusted for repetitive use.

This chain clamp is constructed of high-grade, heat-treated alloy steel for maximum toughness and durability.

There is a classic trigger release made to provide maximum locking force.
