A2020Tii - Allen 20mm Single Tii-On Block
Allen's Tii-On blocks feature a stainless-steel loop at the head of the block. This gives the Tii-On range maximum strength and reliability with minimal cheek separation when tied on and loaded up with a soft shackle. The stainless-steel head loop also ensures the block stays in the right orientation when being used.
When attaching a Tii-on block you must feed the rope around the central axle and through the head of the block. Tii-On blocks rely on the correct attachment method to give them maximum strength.
Becket – The large central rivet not only reduces the overall weight but also offers a rope-friendly attachment, perfect as a tie-off point when being used in a cascade system.
Bearings – Dynamic Blocks feature our patented bearing system which uses twin rows of stainless-steel ball bearings running on a stainless-steel rail. This provides a superior load-carrying ability and longevity when compared to other bearing systems which run on a plastic rail.
