With OOK's patented design, you can hang frames without worrying about wall damage. The antique brass-finished hanger absorbs shock, protecting walls made of wood, sheetrock, drywall, or plaster. The adhesive back allows for easy repositioning, and each hanger includes OOK's Premium Blue Steel Nails. Tested for weight bearing in studs, the Hillman OOK Brass-Plated Blue Hanger Picture Hanging Kit supports up to 50 lbs and comes in a 20-pack.
