About Our Brick

All Bilco bricks are King Size. Each brick has one brick face and one end face. Frogs allow mortar to grip the brick which adds strength to the wall. The back side indicator helps the mason orient the brick.

Eight percent of the bricks in a cube are “corner bricks” that have only one frog. This gives the brick a second brick face to be used in soldier courses, window sills, and row locks. Below is an illustration showing the frogs and backside indicators of bricks in a soldier row. Note the corner brick with only one frog.
