Since this system has no moving parts it is a snap to lock or release with only one hand! The secret is the serrated jam cleat which holds the rope securely in place and for extra security it has a notch to put the rope behind so there is no accidental release of the rope. Then just slide the rope to clear the notch and lift up to release and lower your things with ease. Can lift up to 300 pounds. Comes with 10 feet of solid braid rope and 2 durable metal hooks!
