I bought a new desk online which unbeknownst to me had circular cut outs on the top for cables to run through. These were 3" and 1/8" diameter holes so anything on the table could fall through. I really didn't need or want such great discoveries. So these Cordaway bushings worked and fit perfectly. The light gray matched the same color finish on the table legs that I chose. The opening hole works perfectly. It's very convenient to set up, although I don't need it myself. Very happy with this product.
