Recognize Your Opener
Screw Drive: These openers are connected to the trolley, using a long screw-type rod fitted inside the track. Although they are weather resistant and noisy, they are low-cost and affordable.
Chain Driven: Using a bicycle-style chain, which is connected to a trolley, these openers are extremely reliable and are quite common to be installed indoors.
Belt Driven: These openers are similar to the Chain Driven ones mentioned earlier; these are reliable and quieter compared to the aforementioned ones.
Jackshaft: These openers are wall-mounted at the end side of the torsion bar; they are known for being almost noiseless, elegant and a perfect choice for most garages, especially ones which are smaller in size.
Security Features
For security purposes, make sure to choose an opener device with automatic door lock, mobile alerts when the door is open, motion detection and a battery backup.
