If you mount as described, will it end up hanging above the center of a rig or between two of the bays? Me I have a reel mounted just next to the OH door so it provides air outside or the rear of the bay. Another is at the opposite corner of the bay to handle the front of the rig and the work bench. That works for me because 90% of the work is done in that one bay, yet I can get a hose to most anywhere in the shop from one of hose two locations.
I would not want a hose positioned where it had to be drug OVER a rig to get it where it needs to be. So I have them at the ends of the work bay.
