It uses two 7/32-inch (.225") wire diameter springs and a 93-inch shaft to counterbalance the door curtain, making it easy to open and close. You replace this assembly when the original springs weaken, break, or the shaft binds, causing the door to be hard to lift or not stay open. This is the main lift mechanism for many dry van and refrigerated Whiting roll-up doors.
