PEAK’s Large Iron Retention System (LIRS) is aimed at solving the problems faced when trying to tie on hooks with large wire diameters and long shanks, which often requires the use of heavy threads. The hardened and tempered tool steel anvil/drawbar combination accepts hook wires up to .134″ in diameter. 

The JS2-C1 is equipped with PEAK’s C-Clamp. The clamp is powder coated steel and designed for the 1/2″ vise riser shaft of PEAK’s JS series products and also allows for the use of PEAK’s 3/8″ accessory shaft. This clamp also has rabbeted jaws that can be reversed for maximum table thickness adjustment. The jaws ride on parallel guide rods and do not rotate when adjusted so they won’t mark your table or “walk” when you tighten the clamp. Wrench for tightening clamp is included, vise riser is locked in place with a large comfort-grip hand knob.
