Description
20mm Single Ti3-On Dynamic Block.
The A2020Ti3 has been developed for the paragliding and kiting industries but is now being used in the marine sector.
This block features a wider opening and flatter sides when compared to the older A2020Tii. This design results in an easier block to thread webbing strap and rope around. The block still fits in the same footprint as the older A2020Tii.
Low friction, fast rolling, lightweight and strong, The A2020Ti3 is ideal for dinghies, windsurfing, kitesurfing, paragliding and anything else that runs smaller diameter lines.
Our Dynamic range is generally the best choice for applications that require constant sheave movement.
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. This is very important, as it keeps the line load pulling the side cheeks together.
When using a Tii-Shackle, if possible cross the lines. Only use a non-crossed Tii-Shackle on low-load applications.
For further fitting advice please contact us.
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.
Becket – Our 20 & 30mm blocks offer a large central rivet which 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.

Perfect for making the depower system on my kitefoil race bars. They run smoothly (even on sandy beaches). I can splice up to 4mm dyneema relatively easily around the block. And I use 4-6mm rope to run through the pulley.
