replacement parts
I would first call the Catalina factory and see if they have replacement levers and sheaves(the wheel in a pulley or block) for the EasyLock products. So maybe they will direct you to the manufacturer, where you can order what you need. If the manufacturer has gone out of business Catalina may have replacement parts. If that fails, and you finally resort to replacing the whole unit, I would suggest checking Garhaurer Marine, since they make most of Catalina's OEM hardware now. Their deck organizers are very reasonable compared to Harken and Schaefer etc. Their rope clutches are good and were rated best value by Practical Sailor.
