Protectowire SR-502-N Non-Metallic Strain Relief Connector
The Protectowire SR-502N is a non-metallic strain relief connector (cable gland) used wherever Protectowire linear heat detector cable enters a junction box, zone box or end-of-line box. It seals around the cable jacket to give a watertight and oiltight entry and threads into the enclosure with a 3/8 in NPT fitting and locknut.
