Allen 20mm Tie On Double Dynamic Block High-Load with Soft Shackle

  The Allen 20mm Tie-On Double Dynamic Block High-Load with Soft Shackle boasts a stainless-steel head loop for maximum strength and reliability. The loop also keeps the block in the correct orientation while in use. For optimal strength, be sure to attach the block correctly by feeding the rope around the central axle and through the head of the block. Double blocks should be attached with a crossed/thru-line for even more support. However, for low-load applications, a non-crossed Tii-Shackle can be used. The large central rivet reduces weight and is perfect for tying off in a cascade system. The patented bearing system, featuring twin rows of stainless-steel balls on a steel rail, offers superior load-carrying ability and durability compared to plastic rail systems. Upgrade to the high-load version for even faster rolling speeds, higher load capacities, and less friction thanks to the stainless-steel sheave.
