#2 Q:   Can this be mounted on a vertical surface rather than in a ceiling?
A:   Yes. The doors are powered, not gravity operated, so vertical mounting is possible. You want to orient the airlock door to open like a standard house door -- sideways open orientation not up down orientation. Call us if you have any questions about this.
