This 3-hour fire door is required to have a closer.
These things are never fun to install, but let’s get it done.
The kit comes with a paper template that marks everything out, so I use a level to make sure it’s straight, and a punch to mark where I need to drill.
My one complaint with this kit is that it comes with Phillip’s Head screws- torques would definitely work better.
First, I install the closer arm to the top of the door jamb; then I screw the closer to the door.
These screws are a pain to use, but it’s not going anywhere.
Next, I slip the arm over the pinion shaft on the closer.
I adjust the forearm length so that it’s perpendicular at a 90-degree angle to the door- this puts preload tension on the closer.
Then, I tighten the forearm screw to hold it in place.
Finally, I put the main arm screw in to permanently attach the arm to the closer.
Let’s give it a try- you can see how it slams shut at the end.
There’s an adjustment for both the latch and the sweep of the door.
I slow down the latch speed- it shuts so much smoother now.
All that’s left to do is to put on this plastic cover.

  1. I love them adjustment screws…. At work we always had the front door slamming on everybody… I seen a video like this and they said the screws adjusted the speed and pull of the door and easily adjustable so I had to try it out!!!! So now I’ve got the door closing at the perfect speed where two people can make it out without getting blasted by the door lol great for carrying stuff in and out of the building! And so easy!!! It’s something when you learn it’s so nice to know how easy it is! And you can impress anybody by adjusting the doors! Nobody likes getting hit with a heavy door closing too fast lol

  2. #3 Phillips work fine. I prefer Phillips style head over Torx in some applications. One key point to consider here is letting the self-tapping screw to do the work. By allowing the cutting tip to do its intended purpose instead of using the same technique for wood screws you'll increase efficiency and success

  3. What's the poundage on that door? You said it fire rated… so do you know how much pounds it needs to break and open? What's the time to close and latch at 90? Lol. I'm just messing with you, I don't care but I know what the inspector will look for.

  4. I want to put closers on all my exterior doors and the door that goes from the garage to the mudroom. Not only for anti theft but I think they look cool. I’d go for an LCN, Universal products, or a Norton

  5. My commercial door does not close completely. The screws attached to the arm to the door got loose. I tightened the screws so it worked a while then it does not work anymore. I realized the holes where the screws in got bigger, so the screws don't stay. How can I make the holes smaller? Or is there a small aluminum panel that I can attach to the part of the holes and recrew it? My door is a glass panel door. It's not a heavy fire door.
