This was posted by Lawrence Waters on the Truck Floor Training Facebook page, and it was also sent to me by a door hardware consultant / firefighter friend.  Anybody know what it is?

    Hi Lori,

    It looks like the “device” shown in the picture could be an artifact of something called a “Fox Police Lock”—one of the earliest types of door barricade devices to be commercialized. Here is a link to an article

    http://www.nytimes.com/2008/04/27/nyregion/thecity/27lock.html

    Below is a link to a picture of the Fox Police Lock…

    Lock

    Check the top or bottom of the door and may find a plate, that a pin may have use to come out of

    Send picture of it along with entire door picture

    My guess is the hook or catch from an old stile hold open device. Or maybe some kind of fixture for a door security stop of some sort?

    It sure looks to me like an adhesive security plate of the sort that institutions used to secure computer hardware in the 80’s; e.g.: something like the plates from this kit:
    https://www.recycledgoods.com/qualtec-06127-lok-kit-plate-and-cable-computer-security-theft-deterant/

    I don’t know why it would be centered on the back of a door.

      So far, this is the best I see here.
      Have a look at this Cable Organizer by Byte Brothers
      https://www.cableorganizer.com/byte-brothers/lok-kit/

      That is what it is with a few coats of paint. But the fact it is mounted to a door suggests it was re-purposed as some sort of additional lock, or hold open device or alarm the door has opened. Best guess.

  5. Nelson Dayton says:

    Does the hook pull out, maybe with a chain or string attached? Used as a door hold open or a clothes line?

  6. Angela says:

    It’s a grenade. Just keep the pin in it and everyone will be fine.

  7. Edward Ong says:

    made by Qualtec to secure computer

  8. Pete Schifferli says:

    Douglas2 and Edward Ong got it right. Why it is on the door is a mystery, perhaps part of a jerry-built hold open device?
