Automatic garage door openers come from many manufacturers with different designs and horse

powers. It is important to use a garage door opener of sufficient strength to open and close your garage

door efficiently. Garage doors can be very light weighing less than 100 pounds or very heavy depending


on the size of the garage door and the material used to manufacture the garage door. The garage door

springs are the most critical component as they provide the force to open and close the garage door, but

the garage door opener needs to be rated for the size and weight of the garage door you have.
