Yes, I am the ManAboutRacks and they do fit in most gun safes. It really depends on how you have your safe set up though. You've done a nice job with yours.
I ordered two racks from ManAboutRacks a while back and I was really impressed with them. He does really good work and the service was great. When I end up upgrading the safe, I'll be getting a couple more.
I will have to check back in with this thread in a week or so.
My safe is going to look completely different soon since I just had to order a half dozen of those greystone seven gun racks pictured in ZEBRARANGER's post.
