Rod-Loc Insertion Machine

The Rod-Loc Insertion Machine offers contractors a fast and convenient way to set up rod locks and conduit. It runs off of a standard 110 volt outlet and a 70 PSI minimum air supply. Simply place either 3/4” or 1/2” conduit in the cradle and a rod loc on each side, and by the flip of a switch the air cylinder inserts a rod lock on both ends simultaneously of hollow conduit at the perfect inset spacing, eliminating the old timely hammer in method! Footswitch accessory is also available.

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 them which 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.

  • Works for both 1/2″ and 3/4″ conduit
  • Manufactured from 14 gauge galvanized steel
  • Steel bolt secures the Dyn-O-Claw onto the conduit
