I don't have a good picture to illustrate this, but here it goes...

To ensure that I can push the rack all the way back to the wall and also swing it out of the way, I'll situate the rack so that when it's against the wall, the bundle enters the rack from the wall *just* inside one of the rails. Then I put a flat (non-offset) lacing bar as high as I can, usually in the top rack space.

I'll allow a few feet or so for a loop, then tie the bundle to the lacing bar on the opposite side of where the bundle exits the wall, then run the bundle along the lacing bar. The length of the loop will ensure that the bundle doesn't bend much at all.

If I do it correctly, what ends up happening is that the bundle will basically fold up within the rails of the rack when it's pushed back, and as long as there's nothing in the way, you can push the rack all the way back until the rack touches the baseboard. Plus, you can sort of pivot the rack out of the way and the bundle won't be crossing in front of you when you're there for service.

I'll try to get a picture...
