About Me

loriI’m Lori Greene, Manager – Codes and Resources with Allegion.  I can’t tell you how many times I’ve heard an architect say, with passion, “I HATE HARDWARE!” On the other hand, I work with lots of hardware consultants who like hardware enough to work in this industry for 10, 20, 30, 40 years, or even longer (you know who you are!). I also field questions from security consultants, code officials, locksmiths and other facility personnel who have a healthy respect for doors and hardware.

I have worked in the door and hardware industry since 1986, starting with an aluminum storefront company, working with 2 different door and hardware distributors and a manufacturers’ rep agency, and finally joining MPS Sales in 1994.  MPS was the New England representative for several hardware brands that were part of Ingersoll Rand, and in 2001 we became direct employees of Ingersoll Rand Security Technologies.  In December of 2013, IRST’s security-related businesses became a separate company – Allegion.

My current job is to provide support and education on the code requirements that pertain to doors and hardware, as well as working in code development.  I started iDigHardware.com in 2008 because during my career I’ve been asked hundreds of questions, many of them again and again.  You will find many answers on this site (you may want to start with the Articles page), and for specific questions you can contact an Allegion representative in your area who is knowledgeable about the local code requirements.  The Allegion Code Reference Guide may be helpful, and there is also online training available.

Thanks for visiting!

    Lori,

    Very impressive,your website is a world of information! I am going to refer many of our friends who are in doors and hardware business.

    hello lori, interesting site you have here, I don’t work for any business but i have always been into hardware since middle school (6th grade to be exact) and from what I have observed from middle school and got to high school I got hang of it and got started reparing classroom door closers (LCN 4000 series, mixed 4040’s and 4010’s) believe it or not I find fixing doors interesting.

    not many places were you will see a post like this from a 24 year old female

  12. Deb Henson says:

    This is an awesome site!! I saw it right after you started it and it has grown tremendously. I’m going to bookmark it on my desktop. What a wealth of information written in a comfortable, casual, concise, easy-to-understand style. EXCELLENT!!

  13. Tom Jacobs says:

    Lori, stumbled on your site and am very impressed, especially the pictures showing the issues or hardware involved. In the code business we sometimes don’t know hardware like we should, and it helps having somewhere to go to say, “here’s the issue, what do you have that is code-compliant”. I hope you don’t mind my opinions on the site, and I will be happy to give an interpretation from a building code/fire code perspective whenever I can.

  14. Debbie White says:

    After visiting this site throughout the last couple months, I can say I LOVE HARDWARE, lol. This is actually a very good source of information for all hardware people as well as those not in hardware but who just want to know about it. Great job Lori, don’t forget my request on “industry profile” person. Thanks for making hardware somewhat humorous, the pictures are worth a thousand words.

  15. Jason Pulliam says:

    Lori….great site…..it is clear to me that you spend a significant amount of time and effort keeping this site up to date and relevant for a broad audience. Keep up the great work!!!!!!

    Hi Lori,

    I’ve recently moved to Seattle from Vancouver, BC (where I worked for an IR spec company). I have an interview in Seattle tomorrow for their sister company, also IR and am so looking forward to get back to selling door hardware. I’m GAI certified (English and worked in London for Allgood PLC, selling d line and FSB)

    So happy to have found your site. As my site visits increase over the coming months, I hope to be posting and sharing some stories with you. Consider yourself bookmarked!

        Hi Lori,

    Hi Lori,

    Do you have any pictures of Harris’ old VW Rabbit????

    • Lori says:

      No…I think he was driving an Audi by the time I arrived in 1994. 🙂

      But this is a message from Harris: “That 1980 “Black Diesel Rabbit” was a beauty!!! Zero to 60 in about three days, but 40 miles to the gallon. Never touched the brakes, didn’t need them, just turn on the A/C and the car would come to a rather “quick” stop. Those were the good old days!!!”

    • Jess says:

      Hello Mark, its really great that the 4040XP got all the improvements to prevent wearand tear from daily use as well as other brands from “copycatting” the body style.

      where else can you find the Last Closer Needed???? i have always been a fan of LCN closers ever since i was 12 noticed the 4040 using an EDA arm (standard edition) on the classroom door in 6th grade.

      i have an idea that may be a good advantage to LCN and convenient for installers who install the 4040, basically my idea involves the backcheck selection valve and its location.

      another idea i had, (idea from when i was young too, but never did anything about it, that T handle used on H-CUSH arms, why not dip it in tool handle grip rubber (or some soft material) some of these hold open arms i have turned the handles on, ahh, where not too easy to turn and can easilly hurt the user’s hand or fingers.

      -Jess the door (closer)doctor

      (Lori, is it possible I can email with Mark or someone in his Dept at LCN about my ideas?? also feel free to give him my email address.)

      if in case the revise the LCN4040xp or upgrade/update any of the arms mentioned?? I hope I can be of help to LCN and the employees at IR)

  25. Tom Curry says:

    Lori, great site. I am recommending this to every hardware geek I know. I have been in the business for 15 years and within a few minutes I learned and updated valuable knowledge. Everyone interested in learning about our business and how it relates to their jobs should read this regularly. Building owners and facility engineers should have this as their homepage.

    Thank you.

    Hi Lori

    My name is zvika greenberg i am 63 from Haifa Israel.
    I work as a Safety Engineer at Bnai Zion Haifa Medical Center.
    I like very much to write.
    This summer I decided to start writing the “Introduction to Safety Engineering”
    It will be 2500 pages.
    I am now on page 300.
    I started with “Loss Prevention in the Process Industries” from F.P.Lees who was my lecturer at Loughborough University 1984.
    I continued with Hospital Ventilation Systems, Life Safety Code NFPA 101.

    After writing 300 pages I have a view about Standards.

    Now I decided to write about “My Virtual Building”

    It was you who changed my attitude toward my writings.

    Lori, it was great meeting you at the IAPSC conference last week. ( I enjoyed the dinner! )

    GREAT website. I can’t tell you how many people have told me over the years “I have a great website,” but when I looked at them, there was always something wrong. Maybe the info was erroneous, sometimes it was too cursory, too proprietary, or even just too hard to read, but yours is everything you said, and more.

    I’ve already passed it on to a local code expert, who has bookmarked your site, and he doesn’t bookmark much!

    Thanks and keep up the great work.

    Hi Lori –

    I met you years ago at a DHI dinner on City Island.
    I’ve been in hardware since 1996, and doors and frames for 2+ years now in distribution.
    Your website is great for thoroughness and clarity. It’s nice to be able to feel more confident that I am quoting/furnishing a job correctly after confirming something at your site.

  37. Peter says:

    Hi Lori

    I had a confuse about the astragal. I saw many posts here and cannot get the result. As the case above, it had astragal in pair door with two vertical rod on each leaf. I knew the overlapping astragal should not be used. But in NFPA below, if it is in means of egress, shall not be equipped with astragals.

    1) This astragal means any astragal cannot use in pair doors with two vertical rod in each other?

    2) Or only overlapping astragal cannot be used?

    3) Or split astragal or rubber type astragal can be used if it will not conflict the pair door swing in the same direction?

    Since I search many posts but cannot get the answer, hope you can help me. The UL10C fire door is 90min FRP. Thanks a lot.

    6.4.7.1 Doors swinging in pairs, where located within a means of egress, shall not be equipped
    with astragals that inhibit the free use of either leaf.

    • Lori says:

      Hi Peter –

      If you have two vertical rod panic devices on a standard swing pair, you are correct – you can’t use an overlapping astragal. You can use meeting stile gasketing – two pieces of gasketing that meet in the middle, as long as the gasketing does not restrict the use of either door leaf. If the doors are fire-rated, the gasketing must be listed for use on a fire door. If you have double-egress doors, you can use overlapping astragals because the astragals won’t restrict the other door since the doors swing in the opposite direction.

    Hi Lori!
    I am an architect, but I love hardware. I know many of my colleagues hate it or don’t choose to care about that level of detail in their projects. In my mind, the first and most frequent way users interact with a building is by using the doors. If the doors do not function properly, the building does not work on a fundamental level.
    Thanks for the great and informative site and keep up the good work!

    • Lori says:

      No way! An architect who loves hardware?? INCONCEIVABLE! 🙂

      I’m glad you like the site, and thank you for taking the time to comment!

  42. FDH says:

    Hi Lori,

    Great information on your site. I have 30 years of door hardware experience and still learning.

    Thanks and keep it up!

  43. Roy says:

    We are putting a church in a strip mall utilizing 3 side by side stores. The wall between the first two stores was taken down leaving room for the Sanctuary. The wall between this room and the 3rd store has a cased opening in the back and double swinging doors at the front joining these stores. The whole front of all stores is glas with glass doors for each store. I hope that drew a picture for you. Now for my question. Do I have to install panic bars on the entrance glass doors if these doors remain open during occupancy.

    • Lori says:

      Hi Roy –

      If the jurisdiction has adopted a recent version of the IBC (2006 or later), panic hardware would be required for this Assembly occupancy if the occupant load is more than 50 people. One exception to this is that the main door or doors of a place of religious worship can have a key-operated deadbolt instead of panic hardware if certain criteria are met (see below).

      Here’s the section from the 2015 edition (note that previous editions limited this to the main EXTERIOR door or doors):

      2. In buildings in occupancy Group A having an occupant load of 300 or less, Groups B, F, M and S, and in places of religious worship, the main door or doors are permitted to be equipped with key-operated locking devices from the egress side provided:
      2.1. The locking device is readily distinguishable as locked.
      2.2. A readily visible durable sign is posted on the egress side on or adjacent to the door stating: THIS DOOR TO REMAIN UNLOCKED WHEN THIS SPACE IS
      OCCUPIED. The sign shall be in letters 1 inch (25 mm) high on a contrasting background.
      2.3. The use of the key-operated locking device is revokable by the building official for due cause.

  44. Mark Jurcic says:

    Lori,
    Just wanted to thank you for you many Decoded articles. I read them regularly.

    I particularly appreciate you knowledge and references to both IBC and NFPA 101 codes when applying the specific article subject to these model codes. As an architect working within the Dept. of Defense, our code policy (unfortunately!*#&!) selectively use content from these 2 model codes (why?!…I don’t know). Because of this I have to aware of both. Anyways, thanks again.

    Mark Jurcic

    • Lori says:

      Thanks Mark! Sometimes I’m tempted to focus only on the IBC because it is so widely used, but just for you I will keep adding those NFPA 101 references. 🙂

  46. Stuart Garber says:

    is an ansi function F20 okay for an entrance from a corridor to a reception area that has a suite of offices in it ? i specified F20 Entrance function and would like to stay with it, i hope i didn’t make a mistake and should have specified a F13 Corridor Function. i hope the 20 degree thumbturn, etc. isn’t too complicated for them.

    • Lori says:

      Hi Stuart –

      The F20 is code-compliant, so that’s not a problem. I wouldn’t use that function in a location where the general public would need to use the lock, but the office staff should be able to figure out how it works.

      – Lori

  47. Stuart Garber says:

    Thanks. it is generally the staff themselves that use it, or medical students who work there everyday sort of as employees. The outside lever would pretty much stay unlocked during the day. My only fear is someone screw around with a thumbturn, or partially turn it, and that the lock starts working like a storeroom F07 lock. Not worried about code, always free egress single action. It is a schlage LV9453 F20. I used the F04 version for individual offices in the suite in a DIRTT Office Front System.

  48. Stuart Garber says:

    and which function would you specify, and why ? thx.

  49. Stuart Garber says:

    I am kind of hoping they could unlock it (all the way) with a key outside in the morning, and it stays unlocked all day unless someone plays with the thumbturn inside. It is in a very secure building on the 14th floor.
