A2040TII - Allen 40mm Dynamic Block: Single Tii-On.
The Allen Dynamic range is generally the best choice for applications that require constant sheave movement.
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.
Becket – The 40mm range features a large central hole, which is designed to be used as becket (tying off point).
Allen 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.
