3-1/2 in insulated compression connectors are used to bond 3-1/2 in EMT thin wall 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 compression connectors provide concrete tight connections when taped, 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. Compression connectors are also zinc electroplated for excellent corrosion protection in damp locations. Garvin Industries' labor saving design allows the electrician to quickly tighten these connectors on EMT conduits.
