Selden PBB80 Triple Block with Becket 80 mm – Plain Bearing

The Selden PBB80 triple block with becket (408-001-08) is engineered for extreme load applications where maximum mechanical advantage is required. With three 80 mm sheaves and an integrated becket, this block enables powerful 7:1 tackle systems, making it ideal for heavily loaded mainsheet, boom vang and cascade configurations.

As part of the Selden PBB80 plain bearing range, this block is optimized for high static loads and controlled trimming. It is particularly suited for larger yachts and demanding rigging systems where durability, safety and performance are critical.

The block features three glass fibre-reinforced sheaves with polymer bushings, ensuring smooth rope handling even under extreme loads. The stainless steel reinforcement strap and fibre-reinforced composite cheeks provide high strength, long service life and prevent line jamming.

The swivel head with sliding locking mechanism allows flexible alignment or fixed positioning depending on installation requirements. The becket includes a detachable pin, allowing easy attachment of a spliced eye for secure rigging setups.

With a safe working load of 2000 kg and a breaking load of 4000 kg, this block is built for the most demanding sailing systems.
