A duplex nail is a type of nail that features two heads instead of one, making it easy to remove after use. The second head is positioned above the first one, allowing for easier extraction with a claw hammer or a pry tool. Duplex nails are commonly used in temporary construction, such as for framing or scaffolding, where the materials may need to be taken apart later. They provide a strong hold while allowing for quick removal when the work is finished.
