Child Safety Door Slide

thingiverse

This door slide sits on top of a door. When the door is closed, slide it forward to catch the jamb to prevent the door from opening. The slide is accessible from both sides of the door. This does not require a peg to be screwed in to the door frame like common retail versions. This is for 30mm thick doors and 30 mm thick door jambs. The sealed doors has a longer catch arm to account for the seal.
