Crosby® S-421T / S-421TB Wedge Sockets

  • Wedge socket terminations have an efficiency rating of 80% based on the catalog strength of XXIP wire rope.
  • Meets or exceeds all requirements of ASME B30.26, including identification, ductility, design factor, proof load, and temperature requirements. Importantly, these sockets meet other critical performance requirements, including fatigue life, impact properties and material traceability, not addressed by ASME B30.26.
  • Type Approval certification in accordance with ABS rules for conditions of classificaion, Part 1 2017 Steel Vessels and ABS guide for certification of lifting appliances 2017 available. Certificates available when requested at time of order and may include additional charges.
  • Basket is cast steel and individually magnetic particle inspected.
  • Pin diameter and jaw opening allows wedge and socket to be used in conjunction with closed swage and spelter sockets.
  • Secures the tail or dead end of the wire rope to the wedge, thus eliminates loss or punch out of the wedge.
  • Eliminates the need for an extra piece of rope and is easily installed.
  • The Terminator wedge eliminates the potential breaking off of the tail due to fatigue.
  • The tail, which is secured by the base of the clip and the wedge, is left undeformed.
  • Incorporates Crosby’s patented QUIC-CHECK® 'Go' and 'No-Go' feature cast into the wedge. The proper size rope is determined when the following criteria are met:
    • 1) The wire rope should pass through the 'Go' hole in the wedge.
    • 2) The wire rope should NOT pass through the 'No-Go' hole in the wedge.
  • Utilizes standard Crosby Red U-Bolt® wire rope clip.
  • The 3/8 through 1-1/8 standard S-421 wedge socket can be retrofitted with the new style Terminator wedge.
  • Available with bolt, nut, and cotter pin: S-421TB.
  • US patent 5,553,360, Canada patent 2,217,004, and foreign equivalents.
  • Meets the performance requirements of EN 13411-6.
  • Available with API-2C certification upon request.
  • Wedge sockets meet the performance requirements of Federal specification RR-S-550F, Type C, except those provisions required of the contractor.
  • The S-423T Super Terminator wedge is designed to be assembled only into the Crosby S-421T Terminator socket body. Important: The S-423TW for sizes 5/8” through 1-1/8” (14mm through 28mm) will fit respective size standard Crosby S-421T basket. The 1-1/4” (30-32mm) S-423TW will only fit the Crosby S-421T 1-1/4” basket marked with Terminator.
