So you’re considering purchasing an automatic roller shutter door but you’re worried about access to your garage during a power cut. Fear not. The vast majority of roller garage doors on the market have a manual release which is situated on the side of the motor. Yes, you can open the garage door manually by operating it this way. When the power returns, returning to an automated mode is trivial. Now, if the garage door opening is the only access to your garage, you might share a real concern. Just how are you supposed to gain entrance to the rear of the door if you can’t open the door from the outside? Roller garage doors can be fitted with an external mechanical override switch which will provide a manual mechanism to open/close the garage door during a power outage without sacrificing the security to your garage.
