Dummy Set Function: Dummy sets have no latch or locking mechanism. Typically dummy sets are used as merely a pull on the inactive side of a double door. This is a dummy "set" so it comes with both the interior and exterior handleset. Pair this with a passage or keyed handleset for a complete double door solution. Product Technologies: Solid Brass Construction: Baldwin Reserve Series products are constructed from solid brass - providing a more luxurious, higher quality feel than door hardware made with lesser metals. When you hold a Baldwin product in your hand, you will immediately notice the difference that solid brass makes � it is heavier, stronger, and smoother than most of the door hardware on the market today.
