Adir Corp.613 Vertical File Rolling Stand for Blueprints -

Does this unit come with the clamps or do I need to purchase those separately?

Can I use two different size clamps, i.e. some 24" and some 30"? We are going to use it to store maps in a library.

Does this Adir stand hold Safco hanging clamps (sizes 24", 30", and 36")?

Is the Adir Stand adjustable in height and depth? The Brookside cart says it is, and do not see that in the specs on the Adir. The image looks like it
