Quadrastat controls are fail-safe mechanical devices that "locks where you set it". They automatically lock out feedback forces in either direction without using ratchets, gates, friction pads or unlocking knobs. The greater the feedback force, the tighter the "lock".

The operator can position the control anywhere and never need make a preliminary unlocking motion to reposition the lever.

These control units are industrial derivations of devices originally designed for aircraft flight control systems. The irreversible locking principle has over 25 years of proven application in a variety of extreme environments.
