Barton 35mm Double Block

The Barton Size 2 35mm plain bearing double swivel block with becket is a compact sailing block that delivers quantified load capacity and low weight for deck and control-line use. Its primary benefit is dependable line handling with a 370kg safe working load (SWL) in a 99g stainless-framed unit.

If your boat needs durable hardware that keeps lines under control without excess bulk or complex maintenance this block addresses that problem. It accepts up to 8mm (5/16") rope and provides a simple solution for doubling a lead with a becket while maintaining swivel articulation.

• Double swivel plus becket for fixed mounting and dedicated tail or cleat point
• 35mm x 11mm sheave sized for ropes up to 8mm (5/16")
• SWL 370kg and break load 740kg for verifiable strength
• Lightweight 99g stainless steel internal frame reduces weight aloft
• Plain bearing sheave for straightforward maintenance and robust intermittent-load performance

Compared to ball bearing alternatives this plain bearing block requires less upkeep and handles shock loads reliably though ball bearing sheaves roll with lower friction under continuous high-speed runs. Use this block for mainsheet cascades, halyard leads, reefing systems or control lines where you need a compact double block with a becket.
