Why Manual?
One of the biggest advantages of manual roller shutters is that they can be installed anywhere that has the correct amount of headroom without worrying about power requirements. These doors have a sprung barrel which counterbalances the shutter, allowing it to operate on either system. Push up systems can be manufactured on shutters up to 4m² and hand chain operation is used on shutters up to 30m². This means that ASSA ABLOY can produce a high-quality roller shutter to suit the project requirements, regardless of site location.
