Shunt Enclosure

Model# IRSTW-6

Eliminate the usual difficulties that are associated with accessing couplers or shunts buried between cross ties in the middle of the track. Interrail’s shunt enclosure is constructed of rugged schedule 40 PVC pipe and is installed above ground at a safe distance from the tracks, providing safe and easy access. Inside, the shunt or coupler sits on a support bracket and is attached to the mounting post with sturdy tie wraps. There is enough room inside for two couplers or shunts of 6” in diameter or less.
