How-To Install A Door Closer

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.
