Rod couplers for joining and reducing threaded rod. The collection includes nVent Caddy EM-HEX rod couplers for 3/8", 1/2" and 5/8" rod and a 25R hex rod reducer from 1/2" to 3/8", in electro-galvanized steel.
Use a straight coupler to extend rod runs and a reducer where a heavier rod meets a smaller hanger or anchor. Thread the rod into the coupler to the proper depth on both sides; some couplers have a sight hole to check engagement. Confirm the load rating matches the rod size and the hanger load.
