Because we never know the exact diameter of your mooring line, we provide four inserts that fit in one end of the door. These inserts, once attached via two dovetails in the door, reduce the size of the center hole based on the diameter of the mooring line. If the mooring line was a ½ inch diameter, the insert for a ½ line is used. Other inserts for 5/8” line, 3/4 inch line and 7/8 inch line are provided. A one inch line does not need an insert. The Upgrade Kit consists of a new door, four new inserts and the connecting screw shown here.
