You ought to consider changing your garage door if it’s too old or if it has an older motor or pulley system. The garage doors can be picked out by the type of the chain System they use: chain drive system, screw-drive system, or computer controlled system. The chain drive system is built of a chain that moves the door along a pair of tracks; this is the more common and affordable system but also has the disadvantage of being exceedingly noisy. The screw drive system has a mechanism that actuates the length of a steel rod; it’s a lifting mechanism that’s mounted up in your garage ceiling. The computer drive mechanism does not use whatsoever screws or chains; the system’s body is put on above the door.
