How Do You Buy A Garage-Door Opener?
Sure you could operate a garage door manually, but why would you? Each year 3 million of us buy a remote opener. Beyond dependability, compare cost, safety, security and noise–important for garages that contain workshops or have bedrooms or offices overhead. Step 1 Compare mechanisms. * Chain drives ($130 to $180) are noisy because they use a metal chain along a metal trolley. * Screw drives ($150 to $250) lift the door with a threaded steel rod. Look for the latest models that use a plastic-lined track to reduce noisy metal-to-metal contact and to increase opening speed. * Belt drives ($170 to $350) are the quietest. Their flexible rubber belts dampen vibrations and eliminate the noisy metal-to-metal contact of chain or screw drives. Step 2 Evaluate the openers’ motors. * Some high-quality, efficient openers use a direct current (DC) motor instead of standard alternating current (AC) motor. A DC motor uses less electricity and its speed can easily be controlled, allowing a simpler dr
