Comes with the 4 door latches with posts as shown in the pictures. Bought more than I ended up needing. Last three pictures show what they look like installed. The four locks you will receive are new and unused. To install, all you have to do is place lock over the top of the door, mark, drill hole, and screw the post into your door frame. This type of lock opens from both sides of the door. Let me know if you have any questions.
