All The Door Closers At My School [RE-UPLOADED]

Hey everyone! I just wanted to add on to this video. I could not find another way to add additional video footage to a video that has already been uploaded to YouTube. So, I have decided to re-upload the video of the door closers at my school. The additional video footage includes: Untested fire door closers and includes the door closers at the gym part of the school. I am adding 6 more door closers to this existing video. If you would like to see the original door closer video. I have put a link to the unlisted video down in the comments. [UPDATE: 10/03/2019] I did some recent door closer research. I will try to find the brand name/distributor for all the closers in this video. I will post another update when I figure all the names out.
