USHIN-SHOWA NX / WEST G7510ACTrim lock's Unlocking the entrance door

"Lost key, Unlocking the entrance door"

Many NATIONAL apartments still exist. WEST ACT rim locks are commonly used in this apartment. This time it was a USHIN-SHOWA NX cylinder. The product used is probably compatible with a 40 mm thick door (there is also a product compatible with a 36 mm thick door).

Since it was a rugby ball type thumbturn, this was also completed with normal thumbturn unlocking.
