The flush pulls are installed on either side of the door and the mortise latch/edge pull pull is installed into the side of the door to pull the doors shut easily and can lock into the each other. Locking systems require doors at least 1 3/4 inch thick. The backset on this style of pocket door hardware is 2 1/2 inch. This pattern is called "Traditional Pattern" and features a classic earlier twentieth century pattern that emphasized a more traditional design. Dummy and passage style pocket door hardware is also available. Works with a standard skeleton key and comes complete with an ornate set of skeleton keys. Solid Brass construction for decades of service. Made to be routed into the door - and comes complete with the mounting hardware. Note: The passage and privacy pocket door sets do not come with installation instructions. These sets need to be routed into the door by a professional. The pieces of the set are used as the template for routing the door.
