A unique pivoting cleat that allows the line to run freely until the rope is lifted at which point it cleats. It will release again when the rope is flat on the deck.
Frequently used for spinnaker halyard pump-up systems. The halyard exits the mast, goes through a cam cleat and usually a fairlead. Then there is some space before the halyard runs through the pump cleat. On the line in this space there is a trap handle on a block, which you hold to pump. The tail of the halyard then continues through a fairlead or cheek block and is taken up by shock cord. As you pull the handle, the pump action cleat lifts holding the tail of the halyard, causing the halyard to take up through the cam cleat. As you lower the handle, the pump cleat lies flat again allowing the shock cord to take up the tail through the pump action cleat, readying the setup for another pump if needed.
Designed for use with 4mm line.
Often found and used on 470's, Fireball's, RS700 and many other dinghy classes.
