Selden BBB60 Fiddle Block – 60 mm Ball Bearing Block

The Selden BBB60 fiddle block is designed for efficient rope handling and compact purchase systems on sailboats. Featuring a 60 mm primary sheave combined with a smaller secondary sheave, this block allows increased mechanical advantage in a compact setup.

Equipped with a low-friction ball bearing system and acetal sheaves, the block ensures smooth rotation under dynamic loads. The swivel shackle can be locked at 0° or 90° for optimal alignment, improving efficiency and reducing wear in the rigging.

The glass fibre reinforced composite cheeks provide a strong yet lightweight construction, making this block suitable for both cruising and performance sailing.
