Which end termination uses molten zinc or resin to secure the rope end inside the socket?

• A. Ferrule
• B. Swage socket
• C. Splice
• D. Spelter socket

Answer: (D)

When securing a rope end inside a socket, the method that uses molten zinc (spelter) or resin is a spelter socket. The rope end is inserted into the socket and molten zinc or a resin is poured or injected in, then it cools or cures to form a solid bond that anchors the rope to the socket. This creates a strong, one-piece termination inside the socket.

This differs from a ferrule, which is a metal sleeve crimped onto the rope end to prevent fraying; a swage socket, which relies on compressing the socket around the rope (swaging) to grip it mechanically; and a splice, which joins rope ends together, not secured inside a socket.
