Shutter Fastening Instruction
A non-corrosive countersunk fastener should be placed in accordance with this diagram. The circles represent countersunk screws or you can toe-screw at the x’s. Fasteners should be placed at the top and bottom, then evenly spaced over the length of the shutter as shown. All mechanical fasteners are recommended as screws and should be countersunk and filled with caulk or other fill material and touch up painted.
