This APS E Scow Lifting Bridle is made of 3/16 in fibrous Vectran,. The three legs of the bridle are exactly measured out to properly balance the boat when lifting into/out of the water. It features Wichard Forged D Shackles with a captive pin for attachment to the boat. At the lifting point, there is a 5-1/2 in. loop for easy connection to a crane or for a shackle (depending on your preference).
