ABSTRACT:
A threaded cylinder frame ending at a flange ring and extending in a semicylindrical half sleeve for attachment to another semicylindrical half sleeve. A Locknut with barbs secures and grounds the cylinder frame to the service box wall, and a janus flange ring prevents the connector from passing through the box wall and the pipe from passing through the connector to the box wiring. The length of the half sleeves accommodate random environment movement and retain the pipe within the conduit system. The removable half sleeve allows the pipe to be laid on the catchment area of the main half sleeve and a portal to be formed between the end of the pipe and the flange ring, permitting inspection and repair of wiring.
