Speaking as a husband with a considerable collection of mostly healed head scars, wearing a cap reduces the damage. I'm not familiar with the cabinet doors on the Interstate, but our cabinet doors are held open by a pair of spring struts. The handles on the doors keep them about an inch away from the ceiling when open, and if that is a factor I think there's enough travel in the struts to move the doors the last inch if the handles were removed. If the hardware on your doors doesn't move them far enough, building centers have a variety of strut styles that could improve the situation. If nobody in the Interstate community chimes in, post a photo and I'm sure the collective wisdom of the forum herd can come up with a solution.
