As this looks like a residential product, what happens if I have a hollow core door that are oh so common? Is it universal for a 1-3/8″ or 1-3/4″ door?
Sigh. You know someone is excited to put the kitty litter in the garage and will do this to the rated door between the garage and the house. Even if the literature warns them not to use KittyKorner on a fire-rated door, there is no one around to stop the residents from doing it.
I’m with Lach; most likely these will be hollow core except going to a mud room, garage, or basement (where even in residential, these are sometimes required to be 20 minute). If they are 20 minutes, talk about a code violation. Additionally, how is this any better than a small dog/cat door? Seems like this option would allow cat litter smell to permeate more easily through the house(though hopefully that only happens on rare occasion–I know it happens more frequent than I agree with, but not the point!). Also, if you have a smaller dog that you want to seperate from the cat, this does not resolve that problem either. Finally, if you have children (as I do), talk about a pinch point at just the right height for a crawler chasing the cat! Overall, can’t say as though I’m impressed. Creative, unique, but not impressed.
If one were to take a 20-minute fire door and cut a hole in the bottom of it, to what extent would that affect performance in typical residential fire situations? From what I understand, in most fire situations there will be breathable cool air near the floor for quite awhile even after the air near the top of the door has reached auto-ignition temperature. Would air near the floor typically reach that temperature before the upper part of the door failed?

This is also helpful if the door happens to be too close to a toilet, shower curb or other obstruction… j/k
I have 5 cats, I must try this product on my 1-3/8 hollow core door.
I have to admit, regardless that I am a dog person and not a cat person,,, this is one of the most stupidest inventions I have ever seen.
ah the magic cut machine was on the job again
I am thinking
Someone installs this
Opens it
And hardly ever closes it!!!
Like the high price retractable roofs on stadiums
Just do the corner cut and leave it at that,,,, cheaper
