Thanks boys, we're happy with it too. The doors are 8" high by 9" wide. Not sure how much the units cost however Overhead Doors gave them to us at the same price as their Legacy units.
Yeah, a simple pull of a cord disengages the unit in the event of power failure. The doors are one of Overhead Doors Renaisance line of doors. In fact it is the one on the front of the brochure.
