Thanks guys! I would have called them flanges too (prior to yesterday), but I just wanted to impress Vash with my new "word of the day"
. Crusty, I saw those styles online, but didn't like the appearance (screw holes), and ironically those were the only type that my HD carried. Went down the street to Lowes, and I'm all set now. They also had the plastic split ones (just a slit in the back) that look just like chrome so now I'm back in business...
