Garage door opener equipped with continuous monitoring device
It is really convenient and safe to have suitable device to open the garage door and in fact this type of device is found in three forms namely chain, belt and screw.
The chain drive openers present the oldest styles but still continue to be very popular, the belt drive openers are similar to the former one but with a difference that it is operated with a rubber belt and it is the quietest type of openers and lastly the screw drive openers is someway in-between of the former two mentioned. A standard two car garage door is best served with ½ horse power garage opener. For heavier doors it is better to utilize ¾ horsepower model. The height of standard garage door is 7 feet and the typical opener will accommodate such doors 6” taller than that. All such openers should have a safety mechanism that stops and reverses a closing door when any object passes beneath it. This particular reversing mechanism is very significant it protects from damage to cars, people and pets.
It is better if provision is there with respect of battery backup because if somehow the electrical power is disrupted for some reason then it is the only way to keep the opener functional. Usually a keyless entry pad is mounted just out of the garage door and it is a handy feature because if someone is locked outside the door then it becomes very useful. Considering the new models all come with remote controls with single switch where the door will open only or with the multiple switch options. The warranty period varies from one product to another but one can find products or motors with a warranty period of 10 years.
