Selden Block PBB50 Triple/Becket

The 50 mm Plain Bearing Block – Triple Swivel with Becket is a high-performance rigging block engineered for advanced handling and multi-directional alignment at sea. Featuring a 50 mm plain bearing sheave, this block delivers smooth, low-friction rotation under load, reducing wear on lines while improving control and responsiveness.

The triple swivel head allows the block to orient freely in three axes, providing exceptional flexibility where load directions frequently change — for example on halyards, control lines, travellers and tackle systems. The integrated becket adds a reliable secondary attachment point for snub-ups, tail lines or additional control leads, increasing versatility in complex rigging layouts.

Built for demanding marine conditions, this triple swivel block with becket combines robust construction with dependable performance — supporting efficient and controlled sail handling on both cruising and performance yachts.
