A strong, lightweight range of blocks for use on dinghies and dayboats or as lead blocks on larger craft.
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 more load-bearing balls to be fitted, which ensure extremely low friction performance, even under high loads.
Specifications: Length: 66.7mm Weight: 20g Sheave size 20mm x 8mm (25/32 x 5/16") Max rope diameter: Max rope diameter 5mm (3/16") Max rope diameter: SWL 275kg (606lbs) Break load Break load: 550Kg (1210 lbs) Max rolling load Max rolling load (ball bearing blocks): 130kg (286lbs)
Important note - 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.
