30mm Double Tii-On Block High Load Sheave

The 30mm Double Dynamic Tii-On Block now comes with a High Load Sheave.

Allen's Tii-On blocks feature a stainless-steel loop at the head of the block. This gives the Allen 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.
