SKU: A2020Ti3 Category:


Single Ti3-On. The A2020Ti3 has been developed by the Allen design team for the paragliding and kiting industries but is now being used in the marine sector. Featuring a wider opening at the top of the block and flatter sides when compared to the A2020Tii. This design results in a simpler block to thread rope around. The block still fits in the same footprint as the older A2020Tii and makes use of the same three sheave options which are tried and tested across the 20mm range. Utilising the Allen patented dynamic bearing technology of twin rows of stainless-steel balls running on a stainless rail.

    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.
