UPGRADED VERSION - taking to heart feedback from our customers, this new version features a longer hook arm that works even in kitchens with countertop overhangs. It also has greater adhesive surface area for greater security EASY FOR ADULTS TO OPEN, SECURE AGAINST KIDS - The locks can handle at least 20lbs of pull tension, more than enough to keep cabinets locked against kids. Meanwhile, parents and adults can easily open locked cabinets with one press against the spring-loaded latch, without any need for special keys or magnets. EASY AND DAMAGE-FREE INSTALLATION - No tools required These are installed using strong 3M adhesives. You won't need to drill holes and screws into your cabinets, drawers and cupboards, and the adhesives can be removed without leaving marks. This is especially useful for renters. Your furniture won't have to be damaged to protect your curious children. INVISIBLE DESIGN - unlike other magnetic and knob locks, these locks are hidden behind your cabinet and furniture doors, and hidden away from your curious children's attention. Your kitchen and furniture will look just as beautiful without obtrusive safety devices interfering with its aesthetics. ONE SIZE FITS ALL - these latches will fit your cabinetry whether they have crossbars or not, and regardless of size. For cabinets without crossbars, the supplied buckles will lock the latches in place.
