Monitor glass brackets/mounts?

[kuehnau]

Hi, I wasn't sure where else to put this. I took my cabinet apart so I could properly strip it down. When I did there were these strips of plastic that fit into a groove to keep the monitor glass in place. I was looking for it today and I can't find the two plastic strips that were used to hold the glass in place. Is there any place that sells replacements?

Photos would help immensely, I think you need to look for U Channel
