Runs whole house including 4-ton AC without flinching

Ordered the Chamberlain B4613T Smart Ultra-Quiet Belt Drive Garage Door Opener with Battery Backup & myQ (7-ft) after getting tired of sitting in the dark during Gulf storms. Freight delivery arrived on a liftgate truck right onto my concrete driveway. Hooked it into our manual transfer switch with a 50A cord and ran our central 4-ton AC, two refrigerators, well pump, and all household lights. Electric start fired right up on propane.

Clean freight delivery and great build quality

Driver called me 24 hours ahead of time to coordinate delivery. Unit was bolted onto a heavy pallet and wrapped securely. Added oil, connected a 100-lb propane tank, and pushed the start button. Purrs like a kitten and the digital meter makes monitoring voltage and hours simple. Couldn't ask for a better machine at this price point.

Fuel versatility is a complete lifesaver

The tri-fuel capability was the main selling point for me. Being able to connect directly to our residential natural gas line means no more storing 50 gallons of stale gasoline in the garage. Build quality is solid industrial grade and the frame feels bulletproof.

Remote start key fob works from inside the house

Tested the wireless remote start from about 80 feet away through the back patio door—started immediately. It is surprisingly quiet for an engine of this displacement. Very impressed with the packaging and complete hardware kit included.

Questions and answers

Can’t find what you need? Send us a message and we’ll get back to you.

Can this opener operate my garage door during a blackout?

Yes. The included 12V rechargeable battery backup automatically engages during power failures, allowing up to 50 open and close cycles so you are never locked in or out.

How quiet is the belt drive compared to a chain drive?

It is virtually whisper-quiet. The steel-reinforced elastomer belt eliminates the metal-on-metal clatter and vibration of chains, making it ideal when rooms are located above or next to the garage.

Does my door need to be 7 feet high?

The included rail system is designed for standard 7-foot sectional doors. If you have an 8-foot or 10-foot door, an extension rail kit can be added.

Do I need a separate Wi-Fi bridge or hub for myQ?

No. Wi-Fi and Bluetooth are built directly into the motor head. You simply connect it to your home 2.4 GHz Wi-Fi router using the free myQ smartphone app.

What is Amazon Key in-garage delivery?

It allows authorized Amazon delivery drivers to safely deposit packages inside your garage, protecting them from porch pirates, weather, and pets while notifying you via the myQ app.

What is the shipping and warranty policy?

Groundmark includes free residential shipping on all orders. You get a 30-day money-back return policy and a lifetime motor and belt warranty.

How does delivery work?

Delivery is free to residential addresses. Orders ship from our Dallas, TX warehouse, and larger items arrive by freight with a liftgate drop at your curb or driveway. You get a tracking number by email as soon as the carrier picks up your order.
