Description
See it in action
Official LiftMaster look at the Security+ 3.0 garage door opener lineup — quiet drives, battery backup, cameras, and myQ smart control.
Why homeowners upgrade
Power outage protection
Storms happen. With built-in battery backup on equipped openers, you can still open and close when the grid drops.
Nearly silent DC motor & belt
Quiet is why people pay for premium. A reinforced belt + DC motor is built for homes with living space near the garage.
