Individual panels are assembled of components which prevent light from coming through when closed, and each shutter includes tension adjusters, mortised hinges, and radius hinges to assure ease and accuracy while opening and closing. We use wood dowels to assemble our shutter panels to insure life long durability. Similarly, our interlocking “rabidded panels” block out the light and create a stronger shutter.
