CLGR® Closed Spelter Socket G-417 US Type also known as G-417 Spelter Socket, closed spelter wire rope socket and US Type Spelter Socket.
Our G-417 Closed Spelter Socket complies with US Federal Spec RR-S-550E Type B, manufactured from superior forged steel (through 38mm) and cast alloy steel (40mm-102mm) with zinc plated or hot-dip galvanized finishes.
This socket provides 100% efficiency rope terminations for permanent installations including ship mooring systems, mining hoist cable terminations, and cableway transport systems where full rope strength utilization is critical.
The speltered connection ensures maximum strength retention in applications such as permanent anchor line terminations for offshore platforms and elevator cable end fittings for high-rise buildings.
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.
Important safety note: These sockets are designed for permanent tensioning applications only - never use for overhead lifting operations.
