It's funny how some things stick in your mind, and even funnier that I have "hardware memories" from way back. I remember a rumor going around my 7th grade Home Ec class that another class had locked our teacher, Mrs. Cross, out of the classroom, and that she had cried. So sad!
When I started working in the hardware industry, we regularly supplied doors with a 10" x 10" vision lite (type V in the Steelcraft graphic below), which was typically installed approximately 63" from the center of the lite to the floor. This configuration would no longer be acceptable according to some current accessibility standards. The 2003 edition of ICC/ANSI A117.1 states that if a door has a vision lite or an adjacent sidelite which permits viewing, at least one lite in the door or the sidelite has to be located with its bottom edge not more than 43" above the floor. There is an exception for lites with their bottom edge more than 66" above the floor, which would apply to transom lites or residential entry doors with lites at the top.
A few weeks ago someone asked me this question and I answered him directly rather than posting about it on the blog, but then yesterday I saw someone arrive at the site searching for the very same information. So, in case you too have been wondering what "CUSH" means in relation to door hardware, here you go...
I've heard of a break glass switch in relation to security, but this is a new one from one of my favorite sites to look at when I need a break from doors: www.thereIfixedit.com. The site reminds me of some of my husband's handiwork. :-)

Last week I took a trip down to Providence to visit one of my recent projects, the Blue Cross Blue Shield of Rhode Island Headquarters. I had a heckuva time finding it since it was a new address that my GPS didn't recognize, but I found a shuttle bus driver who not only pondered the best route, explained it to me in detail, and then followed me there and jumped out at a red light to run up and tell me to make sure I stayed to the left. I don't know how I could have missed it...it's a gorgeous building in downtown Providence, right on the canal and a stone's throw from the State House. The architect is Symmes Maini & McKee Associates and you can read a little more about the project here.
Back in the day, before my restaurant choices were based on whether the establishment offered crayons, chicken nuggets, and a giant mouse or talking tree, I used to frequent a local cantina. The "naked" door closer on their ladies room door drove me nuts, so one night I showed up with a closer cover, screws, and a set of hex wrenches. As you can probably imagine, they looked at me like I had two heads and made me hand everything over to the bartender.
A couple of weeks ago, someone asked me why hinges traditionally come in pairs. I asked two of my favorite hinge experts - Matt Bouchard and Bob Jutzi, and they both gave me a variation of the same answer. In the 17th and 18th centuries there were 2 hinges on a door, so they were sold in pairs because you'd never use just one. In the early 1950's it was determined that a 3rd hinge would supply additional support and that became the standard. Our industry called that "a pair and a half" of hinges. There's some great hinge history at www.hardwaresource.com in case there's other hinge trivia you've been wondering about.
One of the disadvantages of a shear lock is the noise associated with locking/unlocking. This post has a video of the operation of a shear lock.
A while back I posted a photo of an egress door in an indoor soccer arena, which had nets hanging in front of it. I asked my blog visitors to comment on whether they thought the application was code-compliant or not.
The other day, one of my friends asked me about the new Schlage LiNK, which is a remote access system that connects you to your home from anywhere via cell phone or computer. With the monthly subscription and Z-Wave enabled products, you can remotely control and monitor your door locks, check on your pets with live video, turn lights on and off, and control and monitor your home's heating and cooling system.
I've seen plenty of inventive hold-open devices on fire-rated doors, but I've never seen instructional signage to go along with them! Coincidentally, I received photos of a chain hold-open and the signage for a chain hold-open on the same day from two different people. The photos are not from the same facility or even the same country for that matter.

Just when I think I've seen it all, someone always surprises me. I received this photo today, and at first I couldn't really tell what was going on. Then I realized that the pipe has been cut to length to act as a hold-open. That's a first! When I asked what was holding the pipe in place, I was told that it's the pressure from the door closers! I pity the fool who leans against the door (especially if his friend leans against the other one)! BONK!
That's the question I was asked on Friday..."If someone orders a delayed egress exit device or delayed egress mag-lock, when do they need the 'BOCA' feature?"
Last week, someone asked me about code requirements related to panic hardware on balanced doors. The project in question is in Israel, and apparently the code requirements there do not include any specific requirements for panic hardware on balanced doors. However, the codes used most often in the U.S. do contain applicable requirements.
I'd be rich if I had a dime for every time I explained that panic hardware is required for Assembly and Educational occupancies with an occupant load of more than 100 people (per IBC 2000 or 2003, NFPA 101) or more than 50 people (per IBC 2006 or 2009). Well, maybe I'd just have a bunch of dimes, but I've said it lots of times and sometimes people still have a hard time remembering it. Here's a true story that will help.
I just said to my husband, "I've got to post something *fun* on the blog tonight." I figured that after a couple of very technical, code-heavy posts, we all needed a break. He looked at me like I had two heads...I guess this isn't his idea of fun.
Fair warning...this is going to be one of those posts that makes your eyes glaze over, especially if you haven't had your coffee yet. But since I've seen several people come to my site looking for this information and leaving without it, I need to post about it before the next person comes looking. I'll try to make it as concise as possible, and remember, the red italicized paragraphs are the code excerpts so you probably don't need to read those unless you're really digging into this issue.

There are a thousand ways to screw up a door, so one of my goals with this blog is to help others avoid mistakes I've seen or made myself (yes, I've made plenty).
Some projects require lever designs for locksets and panic hardware that are beyond the selection of standard "vanilla" levers offered by all of the commercial manufacturers. In some cases, even the "European" designs don't fill the bill, especially when special finishes are desired. I've often run into this with museum projects I've specified.
If you regularly check this site to find out what's new and exciting in the world of doors and hardware, you may have occasionally experienced a server error. Yesterday I asked the web hosting company to move the site to a more stable server to avoid these errors, which they agreed to do at midnight. I was very surprised to go to the site this morning and see the website for the Philanthropy Advisors of New York at our URL! Everything seems to be working now, so thank you for your patience.
The 2009 edition of the International Building Code (IBC) contains an important change that's easy to miss if you're not looking for it. I stumbled across it a few months ago when someone asked me about the exception for cross-corridor doors without positive latching in I-2 occupancies.

One of the Top 10 *issues* I've consistently had to deal with over the years is US10B - oil-rubbed bronze finish. This has been the finish of choice when the "antique" or "historic" look is desired, and whenever I'm asked to specify it I make sure that the architect knows what's going to happen after the hardware is installed.
At next month's meeting of the Boston Chapter of the Construction Specifications Institute (CSI), I'll be doing an update on the 7th edition of the Massachusetts State Building Code. The presentation should be about 45 minutes + time for questions, so relatively painless, and the food is GREAT! If you'd like to attend and you're not a CSI member, email Shelley Hudson. Here are the particulars:
If you haven't seen the new Schlage AD Series Electronic Lock, you can check it out at Schlage.com - just click any of the graphics on this post. Don't you think it's time for me to go on another road trip? I can take an AD Series lock with me this time. :-)
Earlier this week with the 8th anniversary of 9/11 approaching, I wondered what was happening at Ground Zero. I checked in with the Metro-NY office of Ingersoll Rand Security Technologies, and learned that their specification department had written the hardware specs for the four new World Trade Center towers, and the retail space that connects the entire project. Ingersoll Rand Integration is involved with the security and access control as well.
A couple of weeks ago, one of our specwriters called to ask me this question and I knew the answer immediately. Then...hmmm...I thought about it, and talked to myself for a while as he sat on the other end of the phone waiting for both of my selves to come to an agreement.
Honestly, I do NOT have a bathroom obsession. It's just a coincidence that once again, a code question came up regarding a bathroom door.
During Chip Falcon's Road Trip we visited Colonial Williamsburg, and you may have seen my slideshow of the doors and hardware there. I received quite a few questions from readers about the hardware at CW, so I sent an email to the Architectural Research Department there and I got a return email from Mr. Kenneth Schwarz, whose title is Blacksmith, Master of the Shop. Ken has been a wonderful source of information about the hardware at CW, and I'm looking forward to meeting him and hopefully getting a behind-the-scenes tour the next time I'm there.
When this photo arrived in my inbox, I immediately thought the panic was mounted in that position to be operated by someone's foot. I couldn't quite wrap my brain around the latching/unlatching situation...I really think it's just being used as a pull bar and that there's no strike installed. On my next road trip maybe I'll swing through Alabama so I can check it out.
One of our specwriters recently received a memo from an acoustical consultant regarding a school project that he was working on. The memo referenced a standard called ANSI-ASA S12.60 - Acoustical Performance Criteria, Design Requirements, and Guidelines for Schools.
I'm not normally the type of person who would ask for fans...what if I didn't have any?? That would stink.
In a post about opening force a while back, I wrote that fire doors do not have to meet the opening force requirements of the accessibility codes and standards. While that IS true, someone recently asked me a question that led to this further explanation.
Just a reminder that the 2009 amendments to the 2005 Connecticut State Building Code and the Connecticut State Fire Safety Code went into effect on August 1, 2009. Connecticut will continue to use the 2003 International Building Code as the basis for their state codes.
Last weekend I opened the door to a sports facility where my son was attending a birthday party, and I saw an interesting (to me) application. My three friends scattered when they saw me whip out the camera...I still don't know why it's so embarrassing to be seen with someone taking a picture of a door, but it seems to be a universal reaction unless you hang out with other hardware people.
When I started working in the door and hardware industry, we regularly installed fusible link louvers in fire-rated doors, as allowed by various door manufacturers' listings. Although fusible link louvers are still available, their use is limited by current codes:
I received this photo the other day and I knew it was the perfect opportunity to talk about application-specific closers vs. universal closers.
During Chip's Road Trip I gave you two opportunities to join in by answering a trivia question. Thanks to everyone who participated! The two grand prize winners are listed below, and will receive a little something from the IR Prize Vault.
One of my (non-hardware industry) friends commented recently that she's been reading this blog and can't believe how complicated doors and hardware are. It's true! There are a thousand ways to screw up a door and I've made my share of mistakes over the years, but at this point I often spot problems from across the room while "regular" people continue to walk through the doors without noticing.
