Product Description

Single Tufnol cheek blocks come in four sizes to work with ropes from 10mm through to 16mm. They can be fixed to decks, cabin sides, etc with four countersunk screws or bolts/machine screws.

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 Holland with solid stainless steel frames and brass bush bearings.
