The special feature of this picture lock is that it is locked in the center hole of the base unit using a special key - either at the top, bottom or in both center holes. In order to guarantee the best possible security, we recommend using it in the bottom center hole while at the same time using picture hooks or similar in the two upper hanging holes.
Suitable for the Classic, Distance, B1 and Conservo magnetic frame versions. A special version of the picture lock BS 4 is available for Protect magnetic frame.
