Don't be a dope, fit this pull rope!
Review by confirmed purchaser
After my electric up and over garage door failed, due to an electric overload trip, for the first time in 11 years, with no other means of access to the garage to reset the trip switch inside it, I realised that no emergency lock release had been fitted. This is a device which enables you to disable the drive motor and lift the door manually, something that I had to do by drilling a hole in the door with a hole saw to enable me to reach the drive motor. After opening the door, the next thing I did was to order a Liftmaster 1702E from Easygates Ltd. It arrived overnight and was simple to fit, about 15 minutes, and works perfectly. If you have no other means of access to your garage, other than through the up and over door, then fit one of these and you'll not be locked out.
