SKU: ATII-LOCK-40 Category:


Ever wanted to easily attach one of our Tii-on blocks via a continuous spliced loop? Well, now you can with the new Tii-Lock-40. Tii-Lock-40 is a small T shaped plastic moulding which fits perfectly into the central hole of our 40mm Tii-on Block. It allows for a continuous spliced loop to be locked into place, with no chance of it shaking free. The new concept was developed to give a quick, easy and strong option for attaching the A2040Tii block to either the boom or deck of a boat. The Tii-Lock-40 also makes replacing the blocks on the RS Aero boom really straightforward.

    I was sceptical but thought I would give this a go as I already have an A2040Tii block. To my surprise, it works well. I like that it can be used either way up. The only downside is you cannot easily use the centre of the block as a becket once the Tii-lock is fitted.
