Barton Size 2 35mm plain bearing pulley block with swivel and becket delivers compact, high-load sheave control for sail handling. With a 35mm x 11mm sheave and a 370kg safe working load this block provides predictable performance for control lines and trim systems.

If you need a low-weight low-maintenance solution for running rigging this block addresses that problem. The plain bearing design keeps moving parts simple while carrying working loads; it accepts rope up to 8mm (5/16) and weighs 60 g so you retain strength without excess bulk.

• Rated SWL 370kg and break load 740kg for measurable load capacity
• Sheave size 35mm x 11mm fits up to 8mm rope; single sheave swivel plus becket configuration
• Internal stainless steel frame with precision components for corrosion resistance
• Plain bearing type for simple low-speed leads; ball bearing variants are available for lower friction applications
• Compact dimensions 93 x 38 x 24 mm and 60 g weight for minimal deck space and mass

Compared to ball-bearing blocks this plain bearing model is lighter and simpler to maintain while still providing high load values for many yacht applications such as control lines reefing leads and trimming. Ball bearing options are offered when rolling friction under continuous load is a priority.
