K-112D is a cast brass key with an antique finish. With our antiqued brass option, each item is done by hand when the order is placed so that all items in your order have the same finish. We do not apply a color to you items but use a chemical process that 'speeds up' the aging process. The final step is to bring out the highlights of you key much the same way that would naturally occur with years of use. The dimensions are 2 5/8" long by 1 1/4" wide. The shaft or barrel is 1 3/16" and the throw or distance from the center of the barrel to the end of the foot is 9/32" long.
