Designed for 500,000 cycles, hinge clamps have swivel contact bolt and reinforced hinge mechanism. Linkage moves clamping arm forward as it pivots into clamping position, allowing clamp to exert nearly perfectly vertical clamping force. Manifold-mounted clamp is available with clamping forces from 500 to 3,200 lb, with optional position sensing. Max operating pressure is 3,600 psi.
