For Rigid Metal Conduit, IMC and EMT.
Types B, HB, AB, RB, SB, SBT.
These O-Z/Gedney specification grade insulated bushings help protect insulated conductors from abrasion during pulling or due to mechanical vibration. They also provide a voltage gradient between the live conductors and ground at the point where conductor insulation is subjected to electrical and mechanical stress. Versions are available for both threaded and threadless rigid metal conduit and IMC and for EMT.
