RCPrince -
Thanks for the thought. The door opening to the media closet is about 84". The rack with the steel ball castors is about 83", leaving me just an inch clearance. There is a small threshold between the main floor and the media closet. Media closet has fake hardwood (which is great for rolling on) but the actual floor (should the rack need any changes/modifications would need to be rolled out to) is actual wood. So I am trying to figure out if there is something VERY thin and yet strong enough to roll the rack ONTO and be able to move it around without denting wood.
Now, if I get rid of the MA base and have one made, that would work, but also would require me to get the rack out of the media closet, which still leave me stuck with what to do in removing it.
Thanks!
