iDH/iHH is 5 years old!

Category: Door Closers,General InfoLori @ 12:25 pm Comments (26)


And you might be the one getting a birthday present! 

Wow – time flies when you’re having fun!  Who would have thought I would have 5 years’ worth of door-related stuff to write about?  Or that so many of you would still be listening?? I first had the idea to start the site my manager agreed to it because a) it didn’t cost anything except some of my late-night time, and b) he doesn’t like to say “no” to me (who does?).  Nobody expected that the site would grow to be the resource that it is.  Thank you for that!

Here are some stats…

  • I have published 952 posts on the site, and 63 pages (some of which are accessed by the tabs at the top).
  • 36 of my blog posts have been published as my monthly column in Doors & Hardware magazine.  Additional articles have appeared in Construction Specifier, Locksmith Ledger, and Life Safety Digest (all of the articles are listed on the articles tab).
  • 4,667 comments have been left on my blog posts – I moderate each comment and respond to many.  Additional comments are left on blog links posted on Facebook, LinkedIn, and Twitter.
  • There are 3,834 photos on the site, and many have been tagged so they can be found using the image search feature (there’s an orange link in the right sidebar for future reference).
  • The Door & Hardware forum on – a discussion group for AHJs, has had 149 individual discussion threads, and thousands of views (there’s an orange link in the sidebar for this too – “Ask an AHJ”).
  • The site currently has 14,000-15,000 visits per month, from all over the world.
  • And the statistic that I’m most surprised about and grateful for – there are currently 989 subscribers!  Almost 1,000 people who are willing to receive an email each time I post something new (4-5 times per week)!  Ok – I know some of you don’t read each and every email, but someone told me the other day that he actually looks forward to receiving them!  I really appreciate this validation that the information I’m posting is valuable to you!  (you can subscribe here)

So here’s how you can have a chance to win a 5th birthday present from iDigHardware.  Send me a photo of a door or hardware that you think readers would find interesting.  It could be a code problem, a special application, something unusual or beautiful (but door-related).  Each photo you send will earn you one entry into a drawing for 1 of 5 Amazon gifts cards worth $50 each!  So clean out your stash and send me an email or use the Submit a Photo link in the right sidebar.  You have until Friday, February 28th at midnight.  GO!

And just so you’re not disappointed that you came to visit and didn’t learn something…here’s a photo quiz, sent to me by David Barbaree of St. Vrain Valley School District What’s wrong with this picture?

Thru Bolts

Here’s a hint, but you have to look very close…


UPDATE: The problem here is that the installer drilled the holes for the closers as a mirror image, but that’s not what the 4040XP template shows.  When he realized the problem, he stuck the thru-bolts in the empty holes and used the wood screws to attach the closer.

    Happy Birthday!

  2. Dave Snell, AHC says:

    The closer is installed w/ SNB’s but the they used wood screws in lieu of machine screws

  3. Brian W. Mead says:

    The closers are mounted with wood screws because the installer drilled the thru bolt holes in the wrong place and didn’t want to drill 4 additional holes in the door. We see this all the time.

  4. Bert Axelson says:

    Speed thread screws with machine thread sex bolts. That’s why I always order TBWMS screw packs with our closers.

  5. Dick Hart says:

    Happy Birthday, hope you have another five years. I always learn something from IHH!

    Hi Lori….

    Congratulations on being 5 years old… again.

    I appreciate your blog and the personal assistance you provide when my readers have questions concerning fire door hardware that I cannot answer.

    Best of luck….

  7. Curtis Meskus says:

    wood screws and sex nuts, hummmm

  8. Rudy Grave says:

    Thru bolts were drilled incorrectly. Wood screws were used in place of machine/thru bolts.

  9. Kristin Bigda says:

    Happy 5th Birthday, from NFPA 80!!

    Cute puzzle. One of the door closers is installed back side out. Turning the closer over for left or right hand would leave the screw pattern the same but the closer body 180 degrees different. The doors in the picture have one of the closers installed back side out for the screw pattern to be mirror imaged of the other door.

  11. Safecrackin Sammy says:


    You dont look a day over four!

    The closer was installed by a highly qualified individual…..

    Wood screws on the closer side but obviously machine threaded sex bolts on the exterior… Its a new thread size… #12x 1/4-20…..

  12. Rich says:

    On further review, the ruling on the field may be different. The second picture is hard to tell, but appears to be the LHR door by the arm position. The problem with that is that the screws are in a different place than the sex bolts (politically correct term is thru bolts) With a bit of imagination, you can just see a couple of the holes under the edge of the closer.

  13. Cda says:

    Congrats happy. 5th

  14. Darren says:

    Wow, wrong screws! It could be worse…machine screws and no thru bolts in a wood door.

  15. John Emry says:

    Lol! common rookie mistake. It’s always upper-right no matter what swing the door is. Using the SRT screws to cover his/her tracks. That closer’s not going to hold out for very long coming out of a gym

  16. bruce young says:

    well, on the pull side of door thru bolt ends are shown and on the closer wood screws appear to be installed. not sure that LCN has developed a thru bolt that receives the combination wood & self drill screw that they had been using before I RETIRED!!
    also, the 2 screws at top of closer on hinge side of closer are wood screws and on the pull side the thru bolts appear below that location. it seems to me that the thru bolts are used to plug holes drilled incorrectly.
    hope I am close.

      Hello my friend…you’re right! The installer drilled the holes for the two closers as a mirror image, so one set was wrong. He filled the holes with the empty thru-bolts and used the wood screws.

    Happy 5th Lori! I’m proud of you! 🙂

  18. Brendan J Daley says:

    I have never met anyone as knowledgeable as you on code, but even bigger is your absolute burning passion to learn more every day.
    Congratulations on five years, may it only be the very beginning of what else is to come.

    More importantly thank you for all you do.

  19. David Barbaree says:

    You’ve got some sharp people visiting your site, Lori. Congrats on 5 years!
    This LHR door had to be re-drilled and plugged per my punchlist, which was extensive for this school remodel. I will have to send you more of these.
