Color coded identification label clearly states the catalog number and minimum-maximum cable diameter range for which the connector is designed|Neoprene sealing grommet firmly but safely grips cable jacket providing strain relief while protecting internal wiring connections against external tension on cable or cord|Steel or teflon washer reduces friction between grommet and connector cap providing even pressure distribution, eliminating leakage resulting from grommet distortion|Large aluminum connectors 1-1/2 in thru 4 in and all steel connectors are constructed with hex head cap|For particularly harsh applications, wire mesh strain reliefs may be used with cord and cable connectors|Provide a liquidtight and strain relief termination for flexible type neoprene, hypalon, and PVC jacketed power or control cord and cable
