Barton Ball Bearing Sheave 64903

A strong lightweight block suitable for use on dinghies, day boats or as lead blocks on larger craft. Each plain bearing block has a precision moulded Acetal Sheave running a large diameter brass centre bearing ensuring free running under the highest of loads.

Fully swivelling head with removable shackle. Cam arms are fully adjustable by moving the locking clevis pin to achieve the correct cleating angle. The range of blocks used in conjunction with relevant fiddles are particularly useful for use as mainsheet, vang tackles or powerful downhauls on dinghies, day boats or light cruising yachts.
