Tylaska Ferrules – Low Friction Rings
Tylaska Ferrules are lighter and smaller than a conventional pulley block. They have become a popular alternative for many applications where traditional blocks once ruled. Instead of rolling on a pulley sheave, the active line with a ferrule merely slides on the inside smooth surface of the ring. Splice another line around the ferrule to attach it. This attachment line is sometimes made as a loop that is put through a pad eye or the toe rail. Frictional losses are not as big as one might think, especially when using low friction line such as Dyneema. In addition to being lighter and less expensive than conventional blocks, ring ferrules are also less prone to failure since there are no pulleys to crack or bearings to foul.
Tylaska are well known in the sailing community for their high end quality sailing hardware. It is dependable and easy to use when you need it the most.
Sky usually stock the ferrules from FR4 to FR22, other sizes are also available by order.
Applications
Tylaska Ferrules are ideal for applications such as barber haulers, spinnaker twings or other uses that have small turning angles and little line movement. They also work great for backstay adjusters when used in a high purchase cascade configuration. Ferrules start having frictional heating and wear problems when there is significant line movement so conventional pulleys are still better for applications such as mainsheet and halyard blocks.
