if u lost your setters a piece of 3/8" nylon rope will get you by until you get another pair, works almost as good. tie a loop in one end for your foot to slide into go up through the springs back down around the outside the springs and back up through again. pull up on the loose end and the rope will sinch up compressing the springs, set the lock and repeat, when done correctly it is very easy to hold the pressure of one spring. good luck.
