FEATURES: Work Supports automatically adjust to the proper height for supporting a workpiece, then lock securely to become fixed rests. Support plunger is held by a precision sliding-fit pressure sleeve that provides incredible accuracy and repeatability. Fluid-advanced Work Supports provide extra loading clearance and are ideal for workpieces that are too light to depress a spring-loaded plunger. The micro threaded-body version shown here is the smallest work support available anywhere. Manifold mounting capability allows space-saving low-height installation. Hardened contact bolt furnished.
