My church still uses the old style florescent lights. After a recent repair the covers due to their age were very brittle and broke. It was hard finding these covers, but by chance I happen upon this website and they had exactly what I needed and at a good price. When I received the covers they were very securely wrapped and fit perfectly.
working great so far

Great product. Looks like it was part of the ceiling fixture. Arrived quickly and was exactly as described.
