CLGR® Open Spelter Wire Rope Socket G-416 US Type also known as Open Spelter Socket and G-416 Socket.
Our G-416 Open Spelter Socket complies with US Federal Spec RR-S-550E Type A standards, manufactured from superior forged steel (through 38mm) or cast alloy steel (40mm-100mm) with zinc plated or hot-dip galvanized finishes.
This open-design socket achieves 100% efficiency rope terminations for permanent installations where visual inspection is critical, including suspension bridge cable terminations, permanent mine shaft guide rope connections, and stadium roof cable net anchorages.
The zinc-poured termination preserves 100% of the wire rope's original strength, making it essential for critical applications such as ski lift cable ends and permanent marine dock moorings.
Available in sizes from 1/4" to 4" (6mm-100mm) to accommodate various cable diameters.
All sockets undergo rigorous testing to ensure compliance with federal specifications for critical infrastructure projects.
Important safety note: These sockets are designed for permanent tensioning applications with regular inspection access - never use for overhead lifting operations.
