20mm Double Dynamic Tii-On Block With High Load Sheave.
Allen's Tii-On blocks feature a stainless-steel loop at the head of the block. This gives Allen's 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.
Bearings – Dynamic Blocks feature Allen's 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.
High Load Sheave – High load blocks feature a stainless-steel sheave. This upgrade offers even faster rolling speeds, higher working loads and lower friction when compared to the standard acetal sheave.
