Mounts onto the square-drive of Helixa torque sensors. Fitted with a precision leadscrew and sprung-loaded runners into which jaws or holding pegs can be inserted (order separately). Tighten the knob to secure specimens.
Recommended for use only with 3 and 6 N.m sensors due to the risk of overloading lower-capacity sensors when tightening the knob.
Opening span: 20 - 100 mm.
