ABB 2TKA00004191 — A plug is supplied with each conduit end piece. Conduit end piece AJ5.20M is primarily used for termination of plastic conduits in concrete casting. Black color is used as a color coding, indicating that the conduit is connected to a electric box at back surface of the element. After casting, the conduit end piece is cut to the desired length at one of the cut-off grooves, and the trunking is continued with a conduit of the same size. The plug protects the conduit from dirt, concrete and foreign particles. Made of halogen free material (IEC/61249-2-21).
