For the Hobie 16 original SS Tracks. It is a basic swivel cam cleat with roller fairlead and Harken aluminum jaw cammatic, mounted on a stainless steel slide. It self aligns with the angle from which the sheet rope is being held for ease of cleating no matter where the crew is positioned. It’s one piece, easy to install, light weight, low profile, interchangeable with left or right side and self aimed at the windward side of the boat. (Tracks vary slightly. May require prying open some tracks slightly).
