Our Stainless Steel Standard "D" Shackles are made with high corrosion resistance stainless steel. These Stainless Steel Standard "D" Shackles have a 5 to 1 WLL which rates our Standard "D" Shackle's WLL at 20% of its Ultimate Breaking Strength. The WLL is the maximum load that should ever be applied and is based on an in-line pull with no shockload. A competent person should make an assessment of the conditions of use to determine the maximum load allowed. Our Stainless Steel Standard "D" Shackle has a screw pin which allows the pin to be removed from the body of the D Shackle.
