Prevent your Screenflex Portable Partitions from closing or moving once they are set into place with Screenflex PaneLocks. They fit right onto the top of each hinge; just twist the rubber-coated knob to lock the panel at any angle. PaneLocks are a great choice when you need to keep your partitions up for extended periods of time. Choose PaneLocks for three-, five-, seven-, nine-, 11- or 13-panel portable partitions.
