The Metal Framed Patented SwingFrame is a Swing Open, Quick Change Display Framing System that Features Hinges and a Sliding Gravity Lock hidden behind the front frame.

This SwingFrame demo shows you how the lock is installed through the side of the metal picture frame SwingFrame and how it works. Demonstration shown is with a SwingFrame metal poster Frame.

You can't tell that it swings open. But if security is still a concern, as an option you can order a side plunge lock that comes with two keys.
