Manufacturer part #: 9000. 
Harken deck organizers lead halyards and control lines aft, allowing crew to sail from the security of the cockpit. The injection-molded composite top plate provides superior impact and UV resistance. Asymmetrical sheaves of glass-filled nylon have flared bases to lift lines up and off the deck, and combine with a proven bearing system to reduce friction.
Organizers are available in two-, three-, four-, or five-sheave configurations and are stackable for multiple mounting options.
