If you are in the market to put in a new garage door opener you are probably wondering what type of opener is going to be the best for you. For residential properties it is going to be best to have either a chain drive or a belt drive opener. The two openers operate on the same principle, the opener itself is on the roof of the garage and then it uses either a chain or belt to lift and lower the door.
The difference between the two is simply that one uses a belt to pull the door up while the other uses a chain. If the door is heavy a chain will be better but in almost all other cases the belt drive is preferred because it is far less noisy!
