Customizable Child Safety Latch
The large end has a tighter fit and acts like the hinge. The small end is the hook or latch. This is great for babies who are just beginning to crawl.
Caution:
This child safety latch is baby resistant, not baby proof. If your child can stand and push up, he/she can eventually get in with persistence. Also be aware that ABS layers can separate and eventually break if the baby puts enough weight into it. This latch will slow your baby down but still keep dangerous kitchen/bathroom supplies in a safer place.
