LiftMaster Model 8550 Garage door Opener

The LiftMaster garage door opener Model 8550 Belt Drive shown at the left takes safety and convenience to an entirely new level. The reliable, integrated battery backup system guarantees access in and out of your garage, even when the power is off. All safety and security features will continue to operate as well.

The 8550 model is also equipped with the MyQ® technology allowing you to control your garage and home lighting from anywhere in the world with a smartphone or computer. The powerhead features soft-start and slow-stop to reduce noise when it operates - a big plus if you have living space near the garage.

The LiftMaster garage door opener auto-force feature constantly monitors the garage door system and adjusts forces to temperature fluctuations, floor height variances, and door trackage movements. The Smart Garage Door Opener® lets you electronically program security codes from the Smart Control Panel® or the powerhead.

The Model 8550 features an enclosed gear case that provides continuous lubrication of the screw-drive mechanism for the smoothest and quietest operation possible. The powerhead delivers 200 watts of light with an adjustable light time delay for your convenience, and the powerhead meets UL235 requirements.

The Protector System® sensors project an invisible light beam across the plane of the garage door opening and automatically reverses the door if anything interrupts the beam while the garage door is traveling downward. The sensing technology will stop the door from closing if contact is made with a person or object and the opener lights automatically activate when the infrared beam is broken.

Security+® rolling code technology assures a new code is sent every time the remote control is used. PosiLock® theft protection assures that once the door is closed, it stays locked unless you send a new valid remote signal or use the manual release handle.

The Model 8550 is HomeLink® compatible with QuickTrain® technology.

We have been following your blog and we have found a lot of useful information in it.

I was pleased that I was able to easily find the proper tall storage cabinet for my garage. I needed lockable storage to keep my toddler away from sharp tools and solvents that my husband stores. Garagetips-101 solved my problem!

Renee M.

I love the detail in your garage building pages. They helped me understand how to engineer a foundation for a garage we are planning that our building department will approve. I had the inspector go to your pages and review what I was talking about. Now, I am studying the wall framing sections, as we plan to build it ourselves this fall. Thank you so much for the great information.

Great stuff on wall framing. I never really understood the on-and-off spacing concepts for the wall studs until I read your explanations.
