Seldén PBB 50 Triple Block with D-Shackle Swivel Plain Bearing

The Seldén PBB 50 triple block with D-shackle is a versatile and reliable plain bearing block designed for medium-sized sailing yachts that require efficient load distribution. This triple block features three sheaves that optimally distribute the load, providing an excellent mechanical advantage when handling sheets, halyards and other loaded line systems. The plain bearing construction offers smooth and reliable operation, even during prolonged use under varying conditions at sea.

The cheeks of this Seldén PBB 50 triple block are manufactured from glass fibre reinforced polyamide, a material that is exceptionally strong and lightweight while also offering excellent resistance to UV radiation and salt water. The stainless steel strap around the block provides additional strength and protects the construction against mechanical stress. Thanks to the locking button, you can easily switch the block between swivel and fixed positions, depending on your specific application on board. This makes the block particularly versatile for various tasks.

The swivel attachment point with D-shackle ensures the block is always optimally aligned with the line direction, reducing line wear and improving operation. The included straight D-shackles with a pin diameter of 5 mm allow quick and secure attachment to eye bolts, mast fittings or other attachment points. With a safe working load of 650 kg and a breaking strength of 1300 kg, this triple block is ideally suited for medium-sized sailing yachts where reliability and performance go hand in hand.
