The Qdos Safety Magnet Lock keeps cabinet doors and drawers completely closed, leaving no gap for little hands to reach into. This means they are less likely to figure out how the lock works. The Qdos Magnet Lock installs with adhesive, unlike traditional magnet locks that require you to remove drawers to drill and screw them in. Adhesive Installation means no drilling and no screwing into your cabinets. (*certain cabinet designs require one screw). The magnet locks can be for an extended time protecting contents from snooping children and even teenagers!
