A belt course is sometimes used between the first and second stories of a building. Such a course is often constructed like the water table. Like the water table or base, this belt course is furred out in order to throw the course into greater relief. In case this furring is not done, the lower edge of the belt board must be rabbeted to receive the top edge of the siding. Frieze boards, too, are frequently furred instead of being rabbeted. More elaborate belt courses are common.
Corner boards and casing edges should be very slightly beveled so that the siding may take a slight squeeze as it is placed. Care in setting frames and in making casing edges true will insure a saving of time in placing siding.
