One of the Quarter Bonds (56mm lap) for walls 1B thick and over when maximum strength is required. The bond is created by alternative courses of Stretchers and Headers and the lap is obtained by a Queen Closer (56mm) that must be placed immediately after the Quoin Header; the face bond must be sectional through the thickness of the wall to avoid internal straight joints. The bond is used for all types of buildings but is costly in labour and materials.
