Garvin Industries Split Collar Grounding Bushings tightly clamp on EMT, IMC or Rigid conduits that require a ground wire to be installed. Their two screw clamp on design offers a more secure bond than traditional screw on or Hinged grounding bushings and can be rotated in place to provide the perfect wire placement position required by the installer. Garvin Industries Split collar grounding bushings also offer a unique Lay-In Grounding lug with set screw that speeds the ground wire placement in tight electrical panels. These grounding bushing offer dual rated aluminum grounding lugs that can be used with copper or aluminum conductors. They also provide a solid insuliner that protects wires and cables from abrasion on the edges of conduit as they are pulled. Their plastic insulator is rated to 150 degrees C. Split body is zinc electroplated providing excellent corrosion protection in any environment.
