Selden PBB80 Double Block with Becket 80 mm – Plain Bearing

The Selden PBB80 double block with becket (408-001-06) is designed for demanding sailing applications where high loads and maximum mechanical advantage are required. The integrated becket allows efficient multi-part tackle configurations, making this block ideal for powerful 5:1 systems in mainsheet, boom vang and cascade setups.

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 heavy-duty rigging systems where strength and reliability are essential.

The block features two 80 mm glass fibre-reinforced sheaves with polymer bushings, ensuring smooth rope handling even under high loads. The stainless steel reinforcement strap and fibre-reinforced composite cheeks provide excellent strength, long service life and prevent line jamming.

The swivel head with sliding locking mechanism allows the block to rotate freely or be locked in position depending on the installation requirements.

With a safe working load of 2000 kg and a breaking load of 4000 kg, this block is built for high-load applications.
