Hi Brad, I'm afraid I don't like the wing nut idea. I would use a better nut. My experience is with wet, dirty, oily, soapy hands trying to change the hight of the saddle rack is a good idea, but wing nuts and me don't get along. I have seen a turn nob nut that might be bigger and easier to use. Also I just thought if the wing nut can touch the saddle it may damage the tack. I love the idea. I love that it swings out away from the loading area. And I especially love the extra divider on the last horse. I personally like the last divider for safety for the last horse. God forbid the trailer was in an accident, at least I would know that the last horse is secure in the last stall and not halfway out the back door, or even worse on top of the horse in front of him.
