Special Features
  • Aladdin Connect – Remotely monitor & control your garage door with your smart device from almost anywhere at any time, while tracking the operation of your door. Since Aladdin Connect is built into the opener, you do not need to add any other hardware. Works in conjunction with your home router.

  • Durable, reliable performance – The strong DC motor operates most properly balanced residential sectional doors up to 10' high and 500 pounds. Model 3120 has an opening speed of 7.0" per second.†

  • Battery backup capable – No more unexpectedly getting locked outside the garage when the power goes out! The battery unit can easily be added to your opener if you so choose.

  • Soft Start & Stop Control – DC technology allows your door to begin and end its movement smoothly instead of abruptly whenever you operate it. This creates less noise and less wear on the door.

  • 6' power cord – While most openers come with a 4' power cord, the Model 3120 cord is 6' in length to compensate for outlets that require longer reach.

  • Dependability – The quality built into a Model 3120 is backed by a Limited Lifetime Warranty** for the motor and 15 years for the belt drive rail (5 years for the chain drive rail.)

  • Smart lighting – The Model 3120 comes with lighting on each side of the powerhead to help spread light around the entire garage.

  • GenieSense™ monitoring – Automatic force profiling and diagnostic technology improve safety by stopping operations when significant changes occur.
