The new Gripple is an easy-to-use device that offers a fast, secure method for joining, tensioning, and terminating wire cable. Installed in seconds, Duro Dyne Gripple and Hang Fast systems can be correctly assembled without tools to hang ventilation and HVAC ducting and equipment. Significant productivity gains can be made versus traditional threaded rod and trapeze suspension. Gripples are easily adjustable to insure level ducting. They are also ideal for termination of seismic restraints, eliminating installation difficulties caused by cable clamps.
