Crosby Closed G417 & S417 Spelter Sockets - Range from 4500kg to 1,005,000kg
Crosby Closed Spelter Sockets.
Crosby G-417 / S-417 / CSS-2365


Closed Grooved Sockets meet the performance requirements of Federal Specification RR-S-550E, Type A, except for those provisions required of the contractor.
- Forged Steel Sockets to 38mm, cast alloy steel 40mm to 102mm.
- Spelter socket terminations have an efficiency rating of 100%, based on the catalog strength of wire rope.
- Ratings are based on recommended use with 6 x 7, 6 x 19, or 6 x 37, IPS or XIP (EIP), XXIP (EEIP), RRL, FC, or IWRC wire rope.
- Strand constructed with minimal number of wires (e.g. 1 x 7) requires special consideration that socket basket length be five (5) times the strand diameter or fifty (50) times the wire diameter, whichever is the greater.
NOTICE: All cast steel sockets 40mm and larger are magnetic particle inspected and ultrasonic inspected. Proof testing available on special order. Drawing illustrates one groove used on sockets 6mm to 18mm. Sizes 20mm to 38mm use 2 grooves. Sizes 40mm and larger use 3 grooves.
