1-1/2 in vandal-resistant zinc plated steel pipes caps are used to protect 1-1/2 in rigid conduit runs that have been stubbed up and temporarily set in place or abandoned pipes. They seal out rocks, dirt, debris and anything vandals may use to clog the conduits that are set on the job site waiting for wire pulls and are zinc electroplated for excellent corrosion protection. Their 1-piece quick setscrew design does not require any taping and will not distort pipe threads.
