KOHLHOFF LOOP® Connectors are lightweight, strong and durable shackles made of a DSK78 loop reinforced with a hard anodized aluminum thimble. The Thimble can be spliced on to the ends of outhauls, sheets or halyards and the loop then acts in the same way as a standard shackle. The KOHLHOFF LOOP® Connectors come with a velcro + diamond knot closure to ensure secure terminations.
