Barton Marine Series 5 54mm Fiddle Swivel Block

The Barton Marine Series 5 54mm Fiddle 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.

Built for repeated line-direction changes under sailing loads. Corrosion-resistant construction suits exposed deck service. Compact hardware helps keep rigging systems organized.

For the Series 5 54mm Fiddle 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.
