Seldén PBB Plain Bearing Blocks

Use a plain bearing block when you need to handle very high, static loads. They are particularly suitable for standing rigging (e.g., on the backstay or shrouds), for halyards, mainsheet systems, and boom vangs. Due to the structure of the plain bearing, the constant load of the halyard tension is distributed over a continuous surface, which increases the lifespan. Blocks play an important role on your sailboat and should therefore always be kept in good condition.
