Profile: Gibson Stainless & Specialty Inc. manufactures stainless steel products and accessories. Our stainless steel threaded conduit is polished to increase corrosion resistance and also provides aesthetic appearance. Our stainless steel pulling elbows are designed for use with rigid conduit to make wiring pulls at 90° bends in a conduit system. Pulling elbows can aid in instances of sharp bends and allow a straight pull in either direction. Our stainless steel insulated bushings are designed for use with threaded conduit to terminate runs and to provide a smooth surface for wire pulls.
