1-1/4in insulated set screw electrical connectors are used in dry locations to bond 1-1/4 EMT thinwall conduits to electrical junction boxes or enclosures. Their plastic throat liner ensures that electrical wires and conductors do not get nicked or skinned by sharp metal edges. Garvin Industries insulated steel set screw connectors provide concrete tight connections when taped and properly secured with the included locknut, and are rated for electrical applications above 600 volts. Their heavy gauge steel construction maintains mechanical protection and solid grounding of the conduit to the designated electrical junction box or enclosure. Additionally, set screw connectors are zinc electroplated for excellent corrosion protection. Set screw connectors are also made with a versatile combination head screw that can securely fasten a conduit to an electrical junction box using a slotted, Phillips, or Robertson head screw driver.
