chris, the double cleats are the small harken's to match the line size of the halyard. the fair lead for the double is a harken 16 mm air block sewn to the tramp a foot or two back. This allows you to hoist in any direction. You should position the 16 mm block so that you can pull the halyard through the jaws and it's always cleated. to release you pull the halyard between the 16 mm and the cleats while pulling on the retrieval line.
