Can these be mounted on an existing shelf rather than the floor

yes. the supports are aimed downward and screwed on the flat part of any surface. so sure why not. They probaly cant be mounted sideways to side walls. JT

Probably not but, that would be a question for the manufacturer. I would just buy 2 units and add the shelfs from the 2nd one to the first. You will end up with a extra set of legs this way but, by being creative you may find a use for them.

I'm sure you can you will need anchor to a wall at the top and use a connector to attach them. Be sure to measure height so you can reach your top shelf .

Yes you could but the shelves wouldn't be spaced evenly. They make a three shelf version of this if that helps.

No. There is a mounting board that you screw into the wall. Then, the shelf sits onto that piece. You can then screw the shelf into the studs for further support. Essentially, it mounts like toungue-in-groove flooring.

You should be able to but there is no way to fasten them together which would require you to be very careful when putting things onto or taking things off of the shelves. Otherwise, you might end up dumping everything off.

I haven't installed these on an oversized shelf, but there definitely should not be a limitation to thickness as these just screw flat onto the side of the shelf. As for how wide, you would really just be limited by maximum allowable weight. Depending on what type of material you are using you might run into some sag issues if you got too wide.

Yes you can. That is why it is described in the Product Description as a stacking shelf!

Yes you can, it work much better and no screw holes. We tried it on one shelf and it works fine.

Not really, the feet give you half an inch maybe. The shelf can be mounted anywhere on the legs though.

The answer is yes, Dane. You can place the shelves anywhere on the legs. The adapters that allow you the place the legs can be applied at one inch intervals, of course you would never want to put them that close together. My husband says placing the bottom shelf 20 inches off the floor might affect its stability a little, but it is a very stable product - just don't put 500 pounds on it. I wanted it for a specific area and be moveable. It works perfectly for me.

I would have to say no as the shelves attach to the sides with hex head screws. The ends of the wire shelves are threaded to accept the screws and I would doubt very much the threading goes much further than needed to mount to the sides.Hope this helps.

I am sure you can....however, I went to my local Home Depot/Lowe's and purchased my additional shelving boards. May not be as pretty; however, they are very functional and a fraction of the cost. I also purchased the shelving brackets there as well. Good luck!

I attached mine to the cabinet floor. It wasn't very difficult to do. Also, by attaching to the bottom, you can adjust the width better to fit the shelf.

Yes I thinkg they can. I had mine on a book shelf for a while, now they are hanging on a wall.

On top of a counter yes...not mounted under a counter unless you built a cabinet to hold them.
