Assess the height of the opening, not the door. Most garages door openings are approximately 7 feet high. If your opening is 8 ft, 9 feet or 10 feet you will need to purchase an extension in addition to the garage door opener. If it is approximately 8 feet buy the 8 foot expansion.
Step Two, Pick the HP:
There are just two horsepower ratings for many garage door openers. 1/2 HP and 3/4 HP.
In case you’ve got an aluminum, aluminum insulated, or fiberglass door that a 1/2 HP is plenty strong to open either one car (7 to 9 feet wide) or a double car (16 feet wide) door.
In case you have a wood door, a door with windows installed in it, a steel door or among those new doors that look as though they are off a classic carriage house I recommend you go with all the 3/4 HP door. (If a magnet sticks to your door it’s steel)
A brand new single automobile carriage design door may use a 1/2 HP opener. In case you’ve got an extra tall door (9 or 10 feet) or a door that is wider than 16 feet I also recommend you proceed with the 3/4 HP doorway. If you’ve got a one-piece door (usually and old door made from wood) I urge a 3/4 HP door. Before buying best garage door opener you need to know few considerations about them in order to do an informed decision.
Step Three, Select the kind:
Chain drive, belt drive, and screw driveway.
String drive garage door openers are what you’re used to. They’re reliable, noisy and usually last a long, long time. They come in many unique sizes. By way of instance, Sears has an economy version, homeowner variations and heavy duty models. These chain drive garage door openers are usually the best value and can be easily sized for you door. You can buy extensions to get the opener for 8 foot and 10 feet.
