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 Dyn-O-Claw is designed to join the cross section of conduits to immobilize them which further strengthens the duct. The Dyn-O-Claw also eliminates any vibration or rattling sound of crossing conduit. Working in conjunction with Dyn-OMate Rod Locks and conduit, Dyn-O-Claws create an effective duct strengthening system and are easier and faster than other alternatives such as ties or welding.
▪ Available for 1/2’’ or 3/4’’ conduit
▪ Manufactured from 14 gauge galvanized steel
▪ Steel bolt secures the Dyn-O-Claw onto the Conduit
