Stay safely attached to the tree you are hunting out of starting the moment you begin climbing until you reach the ground again with the The Safe-Line Treestand Safety System from Muddy Outdoors. This unique system consists of a 30 braided nylon rope with 2 Prusik Knots you can attach to. The knots slide up and down the ropes easily while you climb and descend but will grab the rope and stop you in the event of a fall. Maximum weight capacity: 300 lbs.
