Extreme Duty Soft Shackle 3/8 Factor 55

The Factor 55 Extreme Duty Soft Shackle is a 3/8-inch diameter, 10-inch pull-to-pull shackle built from HMPE Plasma rope with a woven polyester jacket whipped and coated with Fiber Lock. That jacket sits tight to the knot — exactly where abrasion is most likely to attack — giving you protection where it counts most.

The numbers back the design: minimum breaking strength is 43,500 pounds with a working load limit of 8,700 pounds. Factor 55 puts those ratings 25–30% higher than what standard soft shackles on the market deliver at the same size and weight — a claim backed by lab and field testing, not marketing copy. This shackle weighs in at 6.5 ounces, making it a direct lightweight swap for common steel screw pin shackles without sacrificing load capacity.

The shackle drops into standard shackle mount products without modification and works as a general-purpose rigging connector. Engineered, tested, and manufactured in the USA. Color is red. California Prop 65 warning applies — see P65Warnings.ca.gov for details.
