Installed the MK AL-300/400PR-Inside gray recently for an interior access control door. The fit was exact and the gray finish matched the door frame well. It was straightforward to mount, and the locking mechanism is solid without any electronic components to worry about. Good match for standard office environments requiring secure interior doors.
