Sliding door lock MIWA.SL83 → Replaced with Alpha F4056

"Inspection and repair of malfunction of entrance sliding door lock"

The key seems to be hard.It seems difficult for elderly mothers to open and close.It needs to be readjusted, but it was difficult to handle, so I decided to replace it.


This time, I was suffering from the complexity of hole processing by other companies and the adjustment of the height of the sliding door door by an electrician.

Moreover, since it has a screen door, further processing adjustment is required to prevent interference with the thumbturn.After all, it was necessary to expand the hole for the main body, and it was decided to process it with an electric file.

Since there was a limit to the adjustment range, we expanded the adjustment range by overhanging it.
