Specifically for Protect Magnetic Frame. What is special about this picture lock is that it is locked with a special key in the centre hole of the base element - either at the top, bottom or in both centre holes. To ensure best possible locking, we recommend using it in the bottom centre hole and using picture hooks or similar in the two hanging holes at the top.
The picture lock BS 4 for the Magnetic Frame types Classic, Distance, B1 and Conservo can be ordered here.
