U9.HMSD knob full set replacement

"I would like an inspection because I can't lock the thumbturn from the inside."

When I arrived at the site and checked it, it was a phenomenon often seen in HMDs.It is a defect of the spring of the cylinder side unit.

I was about to finish the repair after all, but when I checked it again, the HM standard case was attached to the door thickness DT.

The spindle is also standard size and is longer than the DT.With this, even if the knob on the cylinder side is repaired, it will not work correctly.It seems that this was adjusted by forcibly loosening the screws, so recurrence is unavoidable.

Explaining the installation failure by some vendor, "It is old and may recur, so please replace it all."

There may be a locksmith who cheats with a small hand.

Well, the lock case was a few millimeters thick, so I couldn't take it out easily.After that, install the HMSD that matches the door thickness DT, and you're done. (HMSD has few opportunities to be shipped, but inventory has finally moved.)

I disassembled the lock case again and checked it, but a part of the spring was in a suspicious state, so I replaced it and it was the correct answer.
