Seldén PBB 50 Double Block with D-shackle swivel plain bearing with becket

The Seldén PBB 50 double block with D-shackle and becket is a robust and versatile block from the PBB series (Plain Bearing Block), designed for high working loads on medium-sized sailing yachts. This double block combines the reliability of plain bearings with the added benefit of an integrated becket, which provides an extra attachment point for securing the standing end of a line. This makes the block particularly suitable for building efficient purchase systems on board.

The block cheeks are manufactured from glass fibre reinforced polyamide, creating a lightweight yet extremely strong block. The stainless steel strap around the block provides additional strength and protection against the elements, guaranteeing a long service life. The maintenance-free plain bearings ensure smooth operation, even under heavy loads. The locking button makes it easy to switch between swivel and fixed mode, allowing you to adapt the block to the specific requirements of each application.

The becket makes this double block the ideal choice for creating purchase systems on medium-sized sailing yachts. By attaching the standing part of the line to the becket, you easily build a 3:1 or 4:1 purchase system when combined with a single block. This is perfect for mainsheets, genoa sheets, kickers and other applications where extra mechanical advantage is desired. With a safe working load of 650 kg and a breaking strength of 1300 kg, this block is rated for serious loads. Suitable for lines from Ø8 to 12 mm, ideal for standard sheet and halyard lines on cruising and racing yachts. The PBB series offers outstanding value for money for sailors seeking reliable performance.
