There is often a confusion about the way garage doors open and close. Many people are under the impression that the door goes up and down thanks to the opener. Although this is partial true, it’s not the whole truth. Garage door openers provide the electric power to make these huge panels move. But they wouldn’t be able to move the door without some ‘muscle’ power too. Garage door springs come to fill that void. And so when springs break, the door won’t move – unless you are Goliath.
