Dan Allen of Sakahara Allen Architects sent me these photos, looking for a key-operated surface bolt at least 24 inches long. I couldn’t think of one, so I’m asking for your help.
These doors are serving a church, and there are currently key-operated deadbolts at the bottom of each leaf. The deadbolts are too low for the reverends to reach comfortably. The International Building Code (IBC) and the California Building Code (CBC) allow key-operated locks on certain doors, one acceptable location being the main door or doors serving a place of religious worship. (You can read more about these requirements in this Decoded article.)
So – the locks or surface bolts need to be key-operated, readily distinguishable as locked, mounted at a height that can be operated by the reverends, and fairly easy to install on the existing doors.
