Modifying wire frame slatwall shelves to work with slatwall inserts

I bought these wire frame slatwall shelves from Amazon a few weeks ago.

They seem to be high quality units and are well built. However, I had a problem when I tried to install them in my slatwall, they wouldn't go in all the way. 

The wire supports are too thick to fit into my aluminum slatwall inserts. 

I proved this by comparing the size of the wire against a spare piece of slatwall insert I had. 

I considered returning them but all the other options were either much more expensive, flimsier, or both, so I decided to make them work with my slatwall inserts. 

I put a cutting wheel on my grinder and cut down the supports to fit. 

I mounted the slatwall shelve in my vice. 

Cut it the supports. 

Changed the way it was mounted put a grinding disk in my grinder and ground it down some more. 

My kid took a photo of me grinding it down. 

It now fits in the wall. 

At that point other projects got in the way and this one was put on hold, but I finally got back to it today. 

I repeated the process on the rest on the shelves and they now fit. 

I then loaded up some tools on the shelves.

I love all the storage space this gives me.
