Soft shackles may be used as a lightweight replacement connecting rigging for common steel screw pin shackles. The Factor 55 Extreme Duty Soft Shackles are engineered, tested, and made in the USA under the uncompromised Factor 55 quality standards. Like all Factor 55 rigging products, these shackles have been lab and field-tested to assure consistent minimum breaking strength values. Each Extreme Duty Soft Shackle is constructed of HMPE Plasma rope that includes additional abrasion and UV protection with a woven polyester jacket that is carefully whipped and coated with Fiber Lock. Note how the protective jacket is attached close to the knot, providing as much abrasion protection as possible. For their size and weight, these Extreme Duty Soft Shackles provide an additional 25-30% verified breaking strengths when compared to common standard soft shackles on the market today. WLL and minimum breaking strengths clearly marked. This shackle has a 3/8-inch diameter and a 10-inch length with a working load limit of 8,700-pounds and a maximum breaking strength of 43,500-pounds.
