20mm Double Dynamic Tii-On Block.

Our Tii-On blocks feature a stainless-steel loop at the head of the block. This gives our 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.

Available with or without a Tii-Shackle (soft shackle).

Fitting Instructions – Tii-On blocks rely on the correct attachment method to give them maximum strength.

When attaching a Tii-on block you must feed the rope around the central axle and through the head of the block.

When possible, double Tii-on blocks should be attached with a crossed/ through threaded line. (see pictures for example).

This is very important, as it keeps the line load pulling the side cheeks together. Only use a non-crossed Tii-Shackle on low-load applications.

For further fitting advice please contact us. 

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.
