4" insulated compression connectors are used to bond 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 die cast zinc compression connectors provide concrete tight connections when taped, and are rated for electrical applications above 600 volts. Their heavy gauge construction maintains mechanical protection and solid grounding of the conduit to the designated electrical junction box or enclosure. Compression connectors come with oversized hex compression nuts to ensure an easy wrench installation.
