LOL! Yeah that worried me for a while, Greg, but then I just adjusted to the fact that they were there and was careful not to hit them. I also have some power tools on stands (not visible in the photo) that are stored just in front of the bench that is under the racks. It would take some doing to accidentally hit them. This would not be a problem for the planes stored in the upper slots of the racks. So, if space is an issue, and you are fearful of hitting the lower placed planes, just store a couple up high. I've had this rack for several years, and no planes have been damaged in any way. Just a suggestion...
