Proving mandrels are used to test the circular integrity of a conduit after back filling. Made from high density polyethylene for long durability and inherent lubricity. Each DPM is assembled with galvanised wire rope and aluminium ferrules to create an eye at each end for fixing of rope for hauling. For use in conduits below 80mm please specify whether it is to service a telecommunication or electrical conduit. Custom sizes are also available upon request.
