Closed Spelter Socket
Product Description
Closed Spelter Socket for Steel Wire Ropes
Product Introduction:
Our closed spelter sockets provide a permanent, high-strength termination solution for steel wire ropes. Manufactured from forged or cast steel, these sockets feature a closed eye configuration that accepts shackles, pins, or other connecting hardware. The spelter (zinc or resin) filling process ensures a uniform load transfer along the entire rope length, eliminating stress concentration and maximizing breaking load efficiency. Designed to meet or exceed ASTM, EN, and other international standards, they are widely used in overhead cranes, hoists, marine rigging, bridge suspension cables, and heavy-lifting applications where safety, reliability, and fatigue resistance are critical. Available in various sizes to match rope diameters from 6 mm to over 100 mm, with optional galvanized or painted finishes for corrosion protection. Easy to install with proper socketing procedures, these sockets offer a maintenance-free, long-service-life connection that outperforms mechanical wedge or clamp terminations in demanding environments.
