Description: I saw this weird lock at the escape room I work at. Can you figure out what series it is, and how tall the lock body is?

I started with a reverse image search on the lock. That was enough to identify the series as Simplex 900.

After that, a normal image search for simplex 900 brought up technical details for the same model, including its height.

That gave the full answer as SIMPLEX900_95MM.
