Furring may be necessary to maintain the proper pitch of the topmost siding panel. Should more than one length of undersill trim be required, make a splice as shown by cutting away 1" from the back of the undersill trim and lapping the sections, leaving a 1/4" space between nailing strip sections. If topmost siding panel is trimmed near the butt leg, an undersill trim alone may not be sufficient.
