They are steel or aluminum, about 1" wide and about 3" long, sit flat against a wall and have one screw hole at the top - nothing fancy but super useful. I have some that I purchased at Home Depot about two years ago and they don't have them anymore. I saw some about a year ago in a horse catalog but I get about 30 horse catalogs and can't find the one I saw them in. I can't provide a picture right now of the ones I have due to computer problems but hopefully the description will suffice - I really want more of these hooks as they work for tack and all kinds of barn stuff.
Don't get confused between my personality & my attitude. My personality is who I am, my attitude depends on who you are.
