If you have a nice arched fireplace and would like the Faceplate to conform to the shape to show the nice field stone keystone, then the Cuttable Faceplate is for you. Simply trace the shape onto the Faceplate and use metal cutting snips to cut the Faceplate to size and shape. Making a template is generally the easiest way to transfer the shape. The Cuttable Faceplate does not require a Faceplate Trim Kit.
