Clamps workpieces to a bench or anywhere a 3/4' hole can be drilled. Exceptionally high clamping forces can be obtained.
With the arm free to pivot independently, all levered forces are exerted downward, without any losses due to horizontal slippage from the canting action of the hold-down post. Clamping force is infinitely variable by tightening the clamping knob.
Fine barb-shaped grooves on the post resist upward forces.
10' post, 8' clamping capacity, 8' throat capacity.
Arm and body made from ZA-12 alloy.
Machined steel post.
Solid brass clamping knob.
