Description
20mm Single 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 soft shackle.
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.
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, 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.
When using a Tii-Shackle, when possible cross the lines. Only use a non-crossed Tii-Shackle on low-load applications. See the picture above of the block attached to a lacing eye for example on how to cross the Tii-Shackle.
