GNB’s Commercial Door Lift Controls

A door that doesn’t open isn’t much good. That’s why we use high-quality Garage door openers from trusted brands like LiftMaster, Micanan, and Manaras – brands we know can keep up with your work schedule, and ours. Capable of heavy lifting with minimal maintenance, these overhead door openers can be controlled by remote, manual buttons, or pull chains.

At GNB Doors, we offer a wide variety of overhead door openers that are designed to fit your specific commercial needs. Depending on how heavy your door is, how often you use the door, the expert door team at GNB will offer you some solutions. Each solution will open at different rates and with different buttons, but whichever one you settle on should fit best with your practices.

We’ll help you choose the right motor for you, factoring in speed, power, purpose, reliability, and price for your overhead commercial door opener. No matter which one you choose, know that it’s backed by GNB’s comprehensive guarantee and it’s covered under our maintenance packages – keeping your doors moving for years to come.
