Is it universal for a 1-3/8″ or 1-3/4″ door? Vivian Volz July 27, 2018 at 11:42 am - Reply 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. Krystina July 27, 2018 at 2:40 pm - Reply 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.

Robert AHC July 28, 2018 at 1:58 am - Reply 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. curtis meskus July 28, 2018 at 8:56 am - Reply ah the magic cut machine was on the job again Cda July 28, 2018 at 11:20 am - Reply 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 John Payson July 31, 2018 at 1:17 pm - Reply 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?
