These lovely rustic knobs come complete with two escutcheons, and are suitable for use with rim or mortice latches. They have a protective wax coating. Internally, minimal maintenance is required; simply polish from time to time with a brush or cloth. If any items are used externally, an occasional application of a beeswax such as Briwax will help protect and maintain the finish. The knobs measure 45 mm in diameter and 55 mm across the backplate. Priced per pair.
