Question for mechanical/designer folks here - what do you call the middle thing exactly. i know the side cheeks are for allen keys, but what is the middle one called. I know it is meant to be used for servicing or during emergencies, and there are diagrams on the sides of door explaing how to open, but they just say mount tool and rotate, but do not name the key (or tool) or the this mount.
It is for a cabinet key, the thing itself is a quarter-turn lock with square insert.
Square drive I guess? Google square socket
