Barton Marine Size 6 64mm Plain-Bearing Swivel Block

The Barton Marine Size 6 64mm Plain-Bearing Swivel Block is built for sail-control systems that need a strong, compact change of line direction. Barton Marine's plain-bearing block construction uses molded sheaves and corrosion-resistant internal hardware to keep the line running smoothly under load. Through-bolted and riveted construction adds security at the side plates, while the specified swivel, becket, upright, or stand-up configuration suits the intended rigging layout. The block is sized for cruising and racing applications where dependable load handling matters more than unnecessary complexity.

It features high-grade injection molded 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 Marine's ball bearing mainsheet traveller system. Designed around a 64mm (2-1/2") sheave and to work with 14mm (9/16") ropes.

• Plain-bearing design keeps the sheave arrangement simple
• Through-bolted construction adds strength at the side plates
• Corrosion-resistant internal hardware suits marine rigging
• Configuration is matched to the attachment style in the model name

For the Size 6 64mm Plain-Bearing Swivel Block, match the block to the rope diameter and safe working load specified for the model, and keep the lead aligned with the sheave to avoid unnecessary side load. Swivel, becket, upright, and stand-up versions each solve a different rigging problem, so the attachment style should be chosen around the intended purchase or turning point.
