Here's an updated version of an in-depth summary of the code requirements and selection criteria for panic hardware. Feel free to share it with anyone who needs to get back-2-basics on panic hardware and fire exit hardware.
For wide-throw hinges on a door that swings 180 degrees, where 2 inches of clearance is required behind the door to accommodate the trim, what is the required hinge width?
Here's the last whiteboard animation video in the current "Intro to Door Hardware" series...about the design-bid-build process for new construction.
On Thursday, November 12, my coworker (and old college friend!), Bill Lawliss, will be conducting webinars at 11 a.m. and 2 p.m. Eastern. Bill will cover Basic Hardware - products used to hang, secure, control, and protect the door. The webinar offers 1 CEU for AIA members and there is no charge to attend the class.
I have explained door handing hundreds of times during my career. I know some people still use the "butt-to-the-butts" method, but that doesn't work for all door openings because it doesn't take into account whether the door is inswinging or outswinging. I explained handing on this site a while back, but just to make it more fun...
Last week I posted a couple of videos explaining some basic code requirements and terminology for panic hardware. The next videos in the series address a topic that I KNOW many architects and others struggle with (because I've personally explained it at least a thousand times) - lock functions...
Allegion has created several videos using the videoscribe format, including these two about panic hardware. Some of the code information in the "101" video is a bit general and I will eventually make a more in-depth video on this topic (I didn't create the videos below), but what do you think of the format?
This is SO COOL. I LOVE it. I know it probably seems like it doesn't take that much to excite me, but when this hit my inbox, it really made my day...all because Dan Dateno of BR Johnson combined his sketching ability with his career in doors and hardware to illustrate alternate definitions for common door and hardware terminology.
I have been asked about door handing SO MANY TIMES over the years...hopefully with your help we can address the questions once and for all. Leave me a comment if I forgot anything!
Hello Readers! This is my next "Back-2-Basics" piece...if there is anything I should add/change, please leave a comment. And have a great week!
Panic hardware, also known as an exit device (or fire exit hardware when used on fire doors), is designed to provide fast and easy egress to allow building occupants to exit safely in an emergency. Code publications define panic hardware as, "a door-latching assembly incorporating a device that releases the latch upon the application of a force in the direction of egress travel.” Panic hardware may also be used because of durability or ease of use, even when it is not required by code.
When a hardware consultant writes a specification, it’s common practice to sit down and discuss the project with the architect, at least for the more complicated jobs. The topic of lock functions seems to arise at almost all of those meetings – usually someone in the room needs a refresher on how the basic functions work. In fact, when I was teaching our specwriter apprentices a few weeks ago I said, “Don’t ask the architect if he or she wants a storeroom function lock, ask if the door should always require a key to enter.” A manufacturer’s catalog may show 50 different lock functions (or more!) and it’s difficult or impossible to remember how each function works.
This afternoon I had an appointment for acupuncture, and as I was drifting off into a needle-induced temporary coma (if you haven't tried it, you should!) I was thinking about what I should post for Friday. Then I thought about how it seemed like such a short time between my Wordless Wednesday post and planning for Friday's post, and in a sudden epiphany I realized that I had posted the WW post today! I DO know what day it is, and I did write the WW post on Wednesday, but I must have had a senior moment. I went back and changed the date so nobody who visits that post in the future will realize that I messed up. To all of the loyal readers out there, THANK YOU for not saying, "You dummy, it's Thirsty Thursday not Wordless Wednesday!" :-)
