Spelter Sockets

Spelter sockets (also known as poured sockets) are high-efficiency wire rope terminations made by embedding broomed rope strands into molten metal (typically zinc) or resin. These sockets create robust, permanent end fittings capable of achieving nearly 100% of the rope’s rated breaking strength. They are used extensively in heavy-duty lifting, rigging, mooring, and offshore applications. Two main styles are available: open spelter sockets, which feature a fork and pin interface for quick assemblies or field inspection, and closed spelter sockets, which offer fully sealed terminations with maximum strength and corrosion resistance. Hybrid configurations—combining open at one end and closed at the other—offer both flexibility and permanent load capability for adaptable rigging setups.
