For manual systems, the counterbalance spring is the heart of the operation. If your door feels heavy or drops suddenly, it indicates spring tension loss. We safely re-tension barrel assemblies and replace worn chain hoists or jammed hand-wind systems. Our team in Andover ensures your manual doors meet lifting force regulations.
