I am on a tight budget & made a curtain rod out of electrical conduit, but needed to get finials to finish it off. Was unable to find a good easy inexpensive solution on line. Found the site, the #1 stopper can be painted w/ Zinzer primer then painted any color you like. 1.5" screws will go thru the hole to tightly fasten your cabinet knobs. Thank you again for this wonderful product!
