Welcome to the latest and greatest wedge socket on the market today, the Super Terminator Wedge Socket from Crosby. It was designed with two things in mind: 1) make installation easier and more efficient, and 2) produce a wedge socket that's tough enough for use with today's exotic wire ropes (high-strength, compacted, rotation-resistant types). You can now yield a standard 80% efficiency rating (based on published catalog breaking strength of the wire rope being used), and have a simpler installation process at the same time. Proper installation also means you no longer have a "first load" requirement. And even better, you can retrofit your existing S-421T Terminator wedge sockets by simply purchasing a new S-423TW Wedge Kit. Available for wire rope sizes 5/8 - 1-1/4" (14 - 32mm).
