Selden BBB60 Cheek Block Heavy Duty – 60 mm Ball Bearing Block

The Selden BBB60 cheek block Heavy Duty is designed for fixed installations where high loads and continuous use demand maximum durability. Mounted directly onto a flat surface, this block provides a stable and low-profile solution for guiding lines along the deck, mast or cockpit.

This HD version is equipped with stainless steel ball bearings, offering increased strength and improved resistance to wear under sustained loads. Combined with a 60 mm acetal sheave, the block ensures smooth and efficient rope handling with minimal friction, even in demanding conditions.

The fixed cheek design keeps the line precisely aligned, reducing rope wear and improving system efficiency. The glass fibre reinforced composite construction provides high strength while maintaining a low overall weight, making it suitable for both cruising and performance applications.
