Barton Marine N01 230 Double Swivel Block Size 1 30mm Pulley

The Barton Marine N01 230 is a Size 1 double block with swivel, featuring a 30mm (1 3/16") plain bearing sheave designed for versatile rigging applications on sailboats and small craft. This lightweight yet durable pulley block incorporates an internal steel frame for enhanced strength and longevity, making it ideal for sheet and control line systems.

Key Features:

• 30mm (1 3/16") plain bearing sheave for smooth line movement
• Double block configuration with 360-degree swivel for flexible rigging arrangements
• Internal steel frame construction provides superior strength-to-weight ratio
• Suitable for lines up to 8mm (5/16") diameter
• Modern lightweight design suitable for dinghies, day sailors, and small cruisers
• Corrosion-resistant materials for marine environments

The swivel function allows the block to rotate freely, reducing line twist and wear while accommodating changing load angles. The plain bearing design offers reliable performance for moderate-load applications where the simplicity and lower cost compared to ball-bearing blocks is preferred.
