Couplers are used for extending the hollow anchor bars. Couplers can safely transfer the system load, with the faces of anchor bolts bearing against each other to ensure safe energy transfer between the anchor bars and the drill bit without affecting the couplers mechanically.
All couplers are made from quality steel materials which are supplied by qualified suppliers. We refuse second-hand/recycled materials!
