Spelter Sockets

  • Manufactured from molten zinc
  • Used on boom pendants, guylines, raising lines, backstays, lifting bridles and more
  • Design factor of five used to establish rated capacities
Spelter Sockets
Boom pendants, guylines, raising lines, backstays, lifting bridles and more. Those are the uses of our wire rope assemblies, offered in both poured (spelter) sockets and mechanically swaged sockets.  A design factor of five has been used to establish the rated capacities seen in the charts.
Molten zinc is the standard socketing material, however, an epoxy socketing material can be specified. Both have the same Rated Capacity. Steel forgings are used on rope sizes 1/2” through 1-1/2” and cast steel fittings are used for larger sizes. Rope sizes larger than 4” are available on special order. The assembly lengths are measured from the centerline point of the pin for open sockets and the bearing point for closed sockets.
