Crosby S-2131 Trawling Shackles - 4.75 Ton - 3/4 in Size, 22.4 in Length

Product Description

The Crosby S-2131 Western Trawling Shackle is a purpose-built marine-grade shackle engineered for the demanding conditions of commercial fishing, trawling, and heavy marine rigging operations. Constructed from forged steel with a heat treated alloy steel bolt pin, the S-2131 is designed to deliver consistent performance and long service life in wet, corrosive, and high-cycle environments. The 4.75 Ton working load limit and 3/4 in body size make this shackle well suited for mid-range trawling gear assemblies, net rigging, and general marine lifting applications.

The Western trawling shackle profile features a wider bow geometry compared to standard anchor or bow shackles, providing greater bearing surface for wire rope, chain, and synthetic slings used in trawling configurations. The bolt-type pin with nut and cotter secures the connection and prevents accidental disengagement under dynamic loading conditions common in marine and offshore environments. The red painted finish provides a visible coating that aids in identification and offers a base level of corrosion resistance, though the shackle is intended for use with appropriate maintenance practices in marine service.

Key dimensional specifications include a 2-5/16 in inner length, 1-1/4 in inner width, 1-1/4 in jaw opening, 1-7/8 in eye outer dimension, 4-1/2 in overall length, and 3-1/4 in overall width, with a 22.4 mm pin diameter. These dimensions ensure compatibility with standard trawling hardware, wire rope terminals, and chain links used in commercial fishing gear. The S-2131 is part of the Crosby Group's extensive line of rigging hardware and is widely used across marine, offshore, and industrial rigging applications.
