Crosby G-416/S-416 Open Spelter Sockets deliver 100% termination efficiency and a versatile open design for secure high-strength lifting.
Crosby Open Spelter Sockets are robust wire rope terminations designed for high-strength applications where an open termination point is required for connection to other fittings. Like the closed variant, these socket baskets are engineered to accommodate specific wire rope constructions, ensuring a reliable bond when speltered properly.
Constructed from forged steel for smaller sizes (through 38mm) and cast alloy steel for larger sizes (40mm through 102 mm), these sockets offer superior structural integrity. The design features an open body with a pin for versatile connection options.
