Binders even when full is wider in the front and narrow in the back resulting in eventually not fitting in the shelf properly.

Use this to put behind the binders. and it will look nicer from the front.

usable for full size binders with adjustment if not the standard 1" binders.

For the strength issue. (Thanks for the feedback). Use 3 wall loops. I use mine for 9X6 binders so are smaller than full binders so are lighter. I didn't test with full size binders.
