Where to find the mesh inserts?

[Happytrails]

We have had to expand our AV equipment in the front cabinets. We need to purchase the mesh inserts that the manufacturers use on the cabinets that hold AV equipment in order for the equipment to breath and not get too hot.
Does anybody know where this can be purchased?
I guess I could order from the manufacturer but didn't know if it was available anywhere else.
Thanks for your thoughts.

I have seen similar at fireplace shops, might be too heavy duty for what you want.

Go on line to WWW. rockler.com
This is a woodworker store that has all the parts you need. Prices are good and quality is outstanding.

Ace Hardware here in Hampton, VA has it.
