Mandrel \ Proving Pig
Mandrels (also know as Proving Pigs) are used to prove newly laid or empty ducts\conduit to establish if the duct\conduit is damaged before the cable is hauled in.
Our Mandrel range has a working area of 200mm long (the overall length of the Mandrel with its eyes for attaching the hauling rope is 300mm) and the diameter is the ID of you duct less 10%.
We offer either aluminum or wooden Mandrels and can custom make a size and diameter to suit your need.
It is recommended that when using a Mandrel that a drawline is tied both ends of the Mandrel. This will allow you to pull the Mandel back the way it has just gone in should your duct be damaged and the mandrel cannot pass forwards through the damage.
