These heavy duty self-tightening grips with a capacity range of 200 lbf to 2000 lbF (1 kN to 10 kN) are ideal for tensile testing of a wide range of materials. The serrated 55 RC hardened steel jaws ride on rollers instead of sliding along the surface of the housing, as with conventional wedge grips. This unique design prevents jamming and improves gripping characteristics.
The spring loaded jaws open with a highly ergonomic rack and pinion lever mechanism. The smooth and easy operation of the lever greatly reduces operator hand fatigue.
