Which component protects the cable from abrasion at the duct edge?

• A. Dynamometer
• B. Basket
• C. Kellum grip
• D. Fair leader

Answer: (D)

A fair leader is used to protect the cable from abrasion at the duct edge. It’s a short, flexible line placed ahead of or attached to the end of the cable so the main pulling force is transferred through this buffer as the cable enters the duct. This buffer takes the contact with the duct edge, guiding the cable smoothly and reducing sharp-edge rubbing that could nick or wear the jacket. Other items have different roles: a dynamometer measures pulling tension, not edge protection; a Kellum grip and a basket-type grip are devices for attaching and pulling the cable but don’t provide the edge-protection function that a fair leader supplies.
