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 handles. Pair this with passage or keyed door hardware for a complete double door solution.
