3 Piece Erickson Couplings Steel 1/2″ to 4″
Made in USA for Rigid / IMC (ER Series)

Connects two pieces of a threaded rigid conduit when one piece of the conduit cannot be turned. Ideal fitting for retrofits.
Key factors for 3 piece couplings alignment, consistent centerlines, strong threads. Since it is 3 individual components the weight of the fitting should be considered. Malleable fittings are bulky and are 2 -3 times the weight of steel. Due to its low Brinnel Hardness ratings, diecast has been known to deform under stress load and the softness of the threads will loosen over tight.
