Dual Dyn-O-Claw™

Ductwork is often reinforced with conduit to minimize movement caused by positive or negative pressures. These conduits can twist inside the duct during transit or installation. The Dual Dyn-O-Claw is designed to join the cross section of conduits to immobilize themwhich further strengthens the duct. The Dual Dyn-O-Claw also eliminates any vibration or rattling sound of crossing conduit. Working in conjunction with Dyn-O-Mate Rod Locks and conduit, the Dual Dyn-O-Claw creates an effective duct strengthening system and are easier and faster than other alternatives such as ties or welding. The Dual Dyn-O-Claw works for both 1/2” and 3/4” conduit.
