Shared entrance door closer repair

"I want the door closer to be repaired or replaced."

It was the property where I worked on Unlocking the entrance door of OPNUS the other day.It was a call from the owner.It was certainly a door closer that I was interested in, but I never thought I would receive so many requests.

When I checked the site, the arm fixing plate was missing.It only stopped with one screw.It is presumed that the screw had fallen off every time there was a moving event.

There should be a fixing plate in the door frame, but I couldn't find it.The holes are also so-called "stupid", so they need to be reworked.I have a nutter for M6 that I have, but this time I decided to make a new hole and make it a tap stop.

I didn't have a tap drill for M6, so I'm heading to a nearby home improvement store.

After returning, decide where to install and set up the drill and tap.The thickness of the upper aluminum frame was about 3 mm, so there should be no problem.

After installation, I adjusted the position of the arm and door, and this time it was firmly fixed.
