The Safety 1st Adhesive Magnetic Lock system is awesome - totally invisible, highly effective, easy to install. Unfortunately, it's also really expensive! This print allows you to lock both doors of a side-by-side tandem cabinet with one lock: the lock secures the first door, and this door bar restrains the second door behind the first door.
Designed to accommodate 3x #8 screws. I've found this bar works best when placed at the same elevation as the cabinet handle hardware - if you place above or below, it creates a moment about the bar and the cabinet hinges.
Obviously, no warranty implied - use entirely at your own risk. Do not use to protect a child/adult or pet from hazards.
Comments much appreciated! Let me know if you'd like access to the original Onshape source.
