Ferrule

1. Brief Description

Ferrules are used in the holes drilled in PSC sleeprs (either in manufacturing plant or at site) for fixing Check/Guard rails etc. Ferrule is made up of insulating material and is driven in the pre-augered hole of the concrete sleeper in which plate screws are driven in field. These ferrule act as insulator and act as barrier for plate screw to any reinforcement in sleeper to avoid track circuit failure when concrete sleepers are used in Track Circuited Areas.
