Barton Marine Series 5 Fiddle Swivel Block - 54mm

The Barton Marine Series 5 Fiddle Swivel Block – 54mm (MPN: N05 430) is a precision rigging component designed for sailors, cruisers, and commercial boat operators who require reliable load management on deck. This fiddle block combines traditional nautical design with modern manufacturing standards, making it an essential addition to any vessel's tackle system.

Built to Barton Marine's Series 5 specifications, the 54mm fiddle swivel block features a swivel mechanism that eliminates line twist during high-load scenarios, which is critical when working with running rigging under tension. The fiddle design allows users to thread two separate lines through the block, distributing forces and enabling mechanical advantage configurations essential for sail handling and load transfer.

This block is ideal for both cruising sailors managing everyday sail trim and racing crews requiring instantaneous, precise control of sheet tension. Its installation integrates seamlessly into existing tackle systems via standard becket and eye connections found on most modern deck hardware, ensuring compatibility with a wide range of setups.
