Found reference to them in Nov/Dec 1994 issue of Family Handyman magazine. Fulton Corp of Fulton,Il (FultonCorp.com/householdProducts.htm) makes this item and the retail price in 1994 was about $12 each. I called them this a.m. They sell to retailers such as Ace Hardware and TruValue. Local Ace Hardware store can't locate in their reference manuals. Lady at Fulton said I could try Home Trends (800 810 2340). Looked them up on the net and they do have them for about $16.95 each. Don't know shipping cost. Will continue searching and if don't find a better price I probably will order from Home Trends.
