Seldén PBB 80 Triple Block with D-Shackle Swivel Plain Bearing with Becket

The Seldén PBB 80 triple block with becket is the most versatile heavy-duty block in the Seldén PBB 80 series, designed for the highest working loads on larger sailing yachts and racing boats. This triple block combines three large sheaves for maximum mechanical advantage with a becket at the bottom, providing an additional attachment point that is essential for complex purchase systems and cascade configurations. The PBB 80 with becket is supremely suited as part of a multi-part purchase system for mainsheets, genoa sheets or other line systems where extreme forces occur.

The construction of this Seldén PBB 80 triple block is based on cheeks and sheaves made from glass fibre reinforced polyamide, a material that offers an outstanding combination of strength and limited weight. The stainless steel strap encases the assembly and guarantees structural integrity under the enormous forces that occur in heavy sailing applications. The bronze top swivel bushing ensures exceptionally smooth rotation of the swivel attachment point, which is essential for efficient operation under load. The plain bearing provides reliable, low-maintenance operation that withstands the challenges of the marine environment. The locking button allows easy switching between swivel and fixed positions.

With a safe working load of 2000 kg and a breaking strength of 4000 kg, this triple block is rated for the heaviest applications on board. The block comes complete with straight D-shackles with a pin diameter of 10 mm for a secure attachment. The swivel attachment point ensures optimal alignment with the line direction, regardless of the angle of loading. The becket at the bottom makes it possible to attach a standing part or integrate the block into a cascade system, allowing you to achieve the maximum mechanical ratio needed for handling heavy sails on larger yachts.
