No doubt Harken's Decoma Cam Base ﾖ Swivel was inspired by Edward Scissorhands. It features a second cleat for lines led vertically through the base of the swivel. It is frequently used to combine vang or backstay controls in the same swivel base that handles the mainsheet, so the leads rotate to face the trimmer. It was designed to work with Harken's 2 in (57mm) and 3 in (76mm) blocks and ratchets. With rows of Delrin ball bearings, the base swivels freely even under high loads.
