Product 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.

These fiddle Tufnol blocks have two uneven diameter sheaves located in-line. They are ideal for main sheets and other sail boat applications where a mechanical advantage is required.  

Fitted with a fixed bow, they come in two sizes to work with ropes of 10mm and 12mm diameter.
