Description

Tufnol is a traditional laminated plastic material made from phenolic resin and woven cotton or linen fabric.  It is strong and light, and provides an economical, low maintenance and traditional solution for sailing boat blocks.

Our Tufnol blocks are manufactured in the Netherlands with solid stainless steel frames and brass bush bearings.

The double Tufnol block, fitted with a bow, comes in four sizes to work with ropes from 10mm through to 16mm.
