Important – practical service tip

If the door has more than one spring, a broken one often means the other is also at the end of its life – it's worth considering replacing the set then, to avoid disassembling the door a second time and paying for service again.

Safety

Door springs are elements operating under high tension. If you have no experience – entrust installation to a service provider
