£ 29.95 - £ 189.95

Clear

This range of high load cruiser bocks are of rugged construction, featuring high quality injection moulded side plates with all load-carrying components from 316 grade stainless steel. Side plates are through-bolted and riveted for added strength and security.

This good looking and versatile range is designed for use on larger cruising and racing yachts. All are designed for ease of use with Barton’s ball-bearing mainsheet traveller systems.

A comprehensive range of cam cleat, fiddle and fiddle & cam cleat versions are available.

Plain Bearing Blocks
Barton plain bearing blocks have a precision moulded acetal sheave running on a large diameter brass bearing, ensuring free running under the highest of loads.

Ball Bearing Blocks
With Barton’s unique super-low friction ball race systems, featuring acetal sheaves and delrin ball bearings, running on a large diameter centre boss. This allows Barton to fit more load-bearing balls, which ensure extremely low friction performance, even under high loads.

Break Loads
Where break and safe working loads are stated, it is assumed that all sheaves are evenly loaded as in a purchase tackle. Uneven loading, or loading of one sheave in a double or triple block, will severely affect strength quoted. If unsure, please seek further assistance.

Maximum rolling load on ball bearing blocks is the maximum free running load before ball bearings will distort.
