Flip Lock

Flip locks install on the door jam and do no damage to the door.. When the door is closed, the flange is flipped over the door and locks the door. These are great locks for any door that open away from the area you wish to secure. Install them at the top one third of the door and only adults will be able to lock and unlock them. They are also great on outside doors when you want to keep the child from going through twist type locks.
