Hi, we are remodeling an apartment and need to select new door levers for all of our doors. I'm having trouble determining what the best type (dummy vs passage vs privacy) would be for our AC closets. They are just large enough to fit the AC unit, but a small child could definitely sneak in and fit. What is the safest option for these types of doors when you have small children? One closet is one door (about 27" wide) and the other is a double door (less wide, probably like 20" each) in the middle of a hallway. Thank you!
