I got mine from Lowe's. I ordered them online and they were delivered to my local store. I cut mine 20" long to accommodate my boro glass also.
It is helpful when cutting them to setup a stop on the saw to cut them the same length. This saved a lot of time. The one thing I realised after putting my glass in them was I am a glass horder!
I am waiting for my husband to build me a cabinet out of metal, so I have it in an old cabinet right now.
I thought I would have extra slots, but sadly I don't have enough to put my 96 glass in also. So they are still in the old pipe holders.
