Steve Murray from Security Lock Distributors sent me these Wordless Wednesday photos…see any issues?

    HW SET #S27 — MAINT CORR (HM 2’0″ x 7’2″)
    5 EA SPRING HINGES 626
    1 EA PANIC BAR, DUMMY 630
    1 EA ROLLER STRIKE 626
    2 EA DOUBLE CYLINDER D/B 630
    1 EA DOODAD, ELEC 689
    1 EA CONDUIT BLK

    Sounds like a reasonable spec to me. Just slap it all on there, and don’t forget to put a couple extra holes in the latch side of the door for good measure.

    I see 2 Deadbolts, then I dont know whats there on top but looks to me as a Mag Lock, also the Exit device does not latch except if its a mortised/concealed exit device and they just installed a rim latch for decoration.

    I like how it is installed on the stop of the single rabbet frame.

    Dont open the door. Freddy Kruger is behind it !!

    I don’t think those are spring hinges. I believe they are institutional hinges and the back side conduit is probably for a door position sensor. They must really want that door to stay closed. It is most likely a access door to the maintenance area of the tunnel, so is their a code violation?

  6. Todd Wyatt says:

    All doors in the Means of Egress, including exit access doors, are required to provide a clear width of not less than 32″ (2012 IBC 1008.1.1 Size of Doors). While this section does have (8) exceptions, I doubt the door-in-question is serving a dwelling unit or a storage closet less than 10 sf. I have had some AHJ’s allow a non-compliant door like this with signage stating “NO EXIT” as long as there was another compliant door adjacent.

    Actually, I find the tunnel vision photo to be very artistic. Heck with the hardware; can I get an original copy of that jpeg? I want to print and hang it on my wall!

  8. Glenn Younger says:

    Is the exit device just dogged down, or is the latch missing?

    Skinny door

    Or is that the picture??

    I would not have done it this way, but I could actually see this application in a weird way. If that were an air handler type of room and the door was for internal access to change filters. If the handler is running, the mag lock prevents entry. The panic bar is so that it stays latched when closed and easy push to exit. Two deadbolts with no bolt holes in the frame to deliberately prop the door ajar but not to lock shut. (sort of a Lock-out/Tag/out device) If the handler was running, the air pressure could be too great to overcome by pushing the bar (I know, that conflicts with the mag lock unless it is also an interlock) Weird application that I wouldn’t fault completely without more information. The tunnel leads me to believe this is Maintenance space and not normal application. We actually have air handlers that have too great of pressure differential to move the door when they are running. We also have miles of tunnels just like that one.

    I do see a roller strike but Latch is missing. If it was a concealed device, what is the roller strike installed for?

    So as a few people have pointed out, thinner than 32″ is a violation of means of egress. What I don’t get is situations such as pipe chases and mechanical areaways, where the solution is to make the door even worse. I had a project with a 1950s CMU building where existing pipe chases for the institutional restrooms and showers was a space 24″ wide between two glazed CMU walls. Therefore, it had a 20″ door to access the pipe chase. Egress code would render that illegal, so the solution, if we were renovating the existing condition, should be that instead of a 20″ wide full height door that a plumber can just walk out of, we should instead have 20″ x 36″h wall access panels – in the interest of following code for life safety, we need to make getting out of these mechanical areas MORE cumbersome, MORE awkward and MORE dangerous. This doesn’t make sense to me.

    That looks like a Sentrol 2800T hazardous location door contact to me, not a mag lock. This must be a special case confined location that would need a permit to enter anyway.

  14. Martin Badke (aka Lauxmyth) says:

    Mystery to me. I will point out something not mentioned yet. There was a door closer based on 6 holes in the header on the push side. Perhaps it conflicted with that wired in device which I think is a type of door contact.

    Also curious is the lack of frame stops. We can see the hinges so that is the pull side. But on the side with the exit device we also see the edge of the door. Now sure how this can be?? I am guessing the two square items above the thumbturns are strikes for some kind of lock which eludes me but maybe they are small stops welded in place.

    Lori, you and your minions find the most interesting doors.
