Seldén plain bearing block with swivel, smooth-running sheet insert, heavy load-bearing - 40 - 70 mm

From the Seldén PBB series. It can be used as a smooth-running, cost-effective block for sheets and jibs. It's particularly suitable for halyards because the plain bearing can withstand high standing loads. The shackle can be used as a swivel or can be adjusted for length or width.
