Selden BBB60 Single Ball Bearing Block with Cam Cleat – 60 mm

The Selden BBB60 single ball bearing block with cam cleat is designed for trimming systems where quick adjustment and secure line control are essential. This configuration combines a 60 mm ball bearing block with an integrated cam cleat, allowing trimming and locking in one compact unit.

The large 60 mm sheave improves efficiency by reducing friction and wear on the rope, even under continuous use. The sheave runs on Delrin or stainless steel ball bearings, ensuring smooth rotation and consistent performance in dynamic sailing conditions.

The integrated cam cleat allows immediate line locking without additional hardware, making this block ideal for active trimming systems. The cleat arm can be adjusted to different angles for ergonomic handling and optimal positioning.

The swivel shackle ensures proper alignment under load and can be fixed in position if required. The composite construction provides high strength while keeping weight low.

This block is best suited for moderate load applications where control and responsiveness are more important than maximum load capacity.
