    Liftmaster 3800 - Low overhead room doors

    For anyone else who ends up here, I ended up flipping my unit to face the wall instead of facing out, effectively reversing the rotation. I had enough distance from the wall in my application to make this work and still be able to access controls for setting up the door. A bit goofy looking...
