I'm trying to figure out who manufactures the return air grates that go into the floor that are then strong enough to walk on. I'm not looking for anything fancy, just strong and low cost. White or brown would be ok.. I've found a few random sizes online but I'm guessing if I can figure out who actually makes them, then I can find a good source locally or online. I'm also interested if anyone has an idea of what standard sizes are for these..
Thanks,
Jeff
