GRF Closed Spelter Sockets (CSS)

Closed Spelter Sockets (CSS) from Global Rope Fittings provide a highly secure and permanent method for wire rope terminations, incorporating a fully enclosed eye design. Unlike Open Spelter Sockets, which feature an open end for direct attachment of rigging components, these sockets are intended to create a solid connection point for hooks, shackles, or other load-bearing fittings. This design minimizes potential disconnection points and enhances overall safety during heavy-load applications.

Built to meet EN 13411-4 standards, Closed Spelter Sockets offer 100% efficiency, retaining the full breaking strength of the wire rope. The tapered cavity is filled with resin or molten zinc, permanently bonding the rope strands to the socket and eliminating the need for frequent maintenance. These sockets are particularly well-suited for applications requiring high stability and long-term reliability, such as mooring, structural engineering, and heavy lifting projects. For professionals who prioritize durability and precision, the closed spelter socket is an essential component in critical rigging assemblies.
