Textile axle blocks: unique technology
The specificity of Ino-Blocks is that they have a Dyneema® textile pin, a fibre that is eight times lighter than a stainless steel cable of the same resistance. Other than the sheave that is made of high quality anodised aluminium, there are no metal parts (the cheek plates are made of plastic). The IB 3.6 thus weighs less than 50 g for a breaking load of 3.6 tons! Additionally, Dyneema® is very slippery, so the friction between the textile axle and the sheave is minimal: Light weight, resistance and efficiency are the secret of Ino-Blocks !
How to choose the right Ino-Block model
Thanks to their very high resistance, Ino-Blocks are compatible with all applications found on board a sailing boat, within their working load capacity, of course. Are you hesitating between two models because you do not know the block’s working load capacity? Ino-Rope makes it easier with this table that indicates which model of the Ino-Block range to choose from, according to the use of the block, depending on the programme (“racing-cruising” or “performance”) and, on the size of the sailing boat.

Ino-Blocks: specially adapted to high loads
When they are subjected to high loads Ino-Blocks reach their best potential. The higher the tension, the more the textile axle “slides on the aluminium sheave” and the less friction there is. Ranking results: Ino-Blocks’ performance is 5 to 10% superior than ball bearing blocks’. They are also ten times more efficient than a friction ring! Thanks to their high resistance and their minimal friction, our blocks are, therefore, ideal on the mast step and for all block and tackle and cascade systems.
Materials made to last
Besides substantial weight-saving, the benefits of plastic compared to metal is triple. Unlike conventional blocks with a pin and metal parts, Ino-Blocks are not corrosion sensitive. Their lifespan will be even longer if you rinse them with fresh water after each sailing trip. This maintenance is hardly a constraint in comparison with that of ball bearing blocks! Finally, the plastic cheeks protect the deck from impacts.
Custom “blocks”: choose your colours !
The most “exciting” for the end: Ino-Blocks are customisable. For instance, it is possible to match a set of blocks with the spinnaker sheets (red on the port side and a green starboard) or mast step blocks with cheek plates of the same colour as the rope which passes through them. Choose the colours you want upon ordering !
