Hellobee Boards

My grandma had them for her in home daycare and I love them! I haven't gotten any because I totally forgot about them but I might get some now.

we have these on single cabinets (where you couldn't use a lock across two knobs). they are great. we did have one wear out / start to fall off (highly used on our under sink cabinet) but we had an extra to replace it. it didn't actually fall off, just we could see it needed to be replaced.
a bit of a pain to install so I would only put them on cabinets where easier locks wouldn't work. but they do look nice since everything is inside.
