Flex-Arm Childproof Cabinet Hook Latch
A screw-in child-safety latch for cabinet doors with a face frame. It has an 84 mm flex arm that mounts to the back of the door and a 26 mm catch with a 7 mm drop lip that mounts under the face-frame rail. The door opens about 20 mm, then the 7 mm hook stops it until an adult presses the arm down. Both pieces print together on their sides, joined by a snap-off tab, so the arm bends along the layers instead of across them. Mounting holes are 3.9 mm, for #6 (3.5 mm) or M3 pan-head screws.
