Corniced Edge Window Sill Molds

Cornice Window Sill molds feature a corniced edge treatment (shown at left). Whether it be a window sill, a fireplace mantel, or a bookcase shelf, you can cast beautifully contoured corniced leading edge sills. These male molds can be cast quite easily without use of a female, so a female is not offered. To cast, pour the main mold volume normally, let it kick, then lay the mold on its side (it's built to accommodate that), and finish pouring the front lip.

For each of the following, block down using special End Stop Divider Part Number 010866.
