DYNA Grip® Stay Cable System

The DYNA Grip® Stressing Anchorage consists of an anchor block in which the strands are anchored by high fatigue 3 part-wedges. A ring nut is threaded onto the anchor block to transmit the cable force into the structure via the bearing plate. A steel pipe which incorporates bending and sealing provisions for the strands is part of the anchor block. A non-adjustable anchorage with the same provisions for bending and sealing of the strands can be placed at the dead-end side:
