Hi Tracy,

Thanks for your question.

The glass shelves were 12"x24", 1/4" thick, tempered glass, made by a local glass company.
The glass hardware is made by Richelieu. Here is a link:

If the link doesn't work, you can search on their website for "glass shelf supports". There is a vast selection. They are a great resource for all kinds of fancy hardware.

Good luck with your project!
