I have a TV console with glass inserts on the main cabinet doors that house my A/V receiver. I'm forced to keep them open to allow for adequate cooling for the receiver, but I'd like to replace the glass with metal inserts similar to what is pictured here so that I can keep the doors shut and still allow IR remotes to function and adequate cooling. What should I search for? It's not chicken wire, it's not hardware cloth...looking for the proper terminology to feed Google lol. TIA.
