Another Day, Another Zoo…
...Another funky hardware application.
10-Year Warranty
It's true! The new Falcon 24/25 device has a 10-year mechanical warranty (1-year electrical).
Cracker Barrel Shocker!!!
There are almost 600 Cracker Barrel restaurants in the United States and I've been to most of them. Well...not most, but a bunch. The kids like the food and there's a lot of miscellaneous stuff on the walls that we can use to play, "Who can find the _______?" When you drop a whole cup of milk on the floor (like this morning) they don't bat an eye. At least you always know what to expect...every Cracker Barrel has basically the same menu, the same "country store" selling stuff my kids can't live without, the same rocking chairs and checker boards on the porch, and the same entrance doors.
All Aboard!
Yesterday we drove from Front Royal, Virginia to Grassy Cove, Tennessee, which is a VERY long drive. We usually plan on stopping somewhere for the kids to burn off some energy, and yesterday's stop was at the Virginia Museum of Transportation in Roanoke. I can find an interesting (to me) hardware application just about anywhere, and the most interesting hardware I found was in the President's One train car, which was built in 1916. There were double-acting spring hinges, a sliding door on a curved track, and some double-acting deadlatches - all still in working condition. Pretty cool.

Pocket Pivots
I recently received this photo from an architect who wanted to use the Von Duprin Inpact devices pictured here on another museum I'm working on. I've used these several times when an architect wanted the panic device powder coated a similar color to the door. As with LCN closers, Von Duprin panic hardware can be powder coated in a multitude of colors (refer to the Tiger Drylac brochure called RAL Exterior/Interior).
Rod Guards
I'm a big fan of creative hardware applications like these PVC rod guards on an exterior pair in a high school, but I think they should have considered adding some bottom latch guards. The latches don't even have their covers! FYI...Von Duprin does manufacture rod and latch guards - the RG-27, also available as a rod guard only (RGO), a latch guard only (LGO), or an extended latch guard only (LGO-3' or 4').
Astragals with Vertical Rod Panics
An astragal is a piece of molding used on a pair of doors or between the top and bottom leaves of a Dutch door, to provide security, protect against weather conditions, prevent light or sound transmission, or to retard the passage of smoke, flame, or gases during a fire. On a Dutch door the astragal is used to close the bottom leaf in conjunction with the top leaf. An astragal should not be confused with a mullion, which sits between (fixed) or behind (removable) the meeting stiles of a pair.
High Security Dogging
I think this photo speaks for itself. I just love the creativity and the lengths people will go to with these modifications. It's kind of sad that I get my kicks from looking at doors gone wrong, but admit it...you do too!
Retrofit Dogging
I've spent several phone calls this week discussing "dogging" with one of my favorite clients. I guess it is kind of hard to keep straight if you're not a hardware person. The term "dogging" refers to holding the latch(es) of a panic device retracted to create a push/pull function. When the panic device is dogged, it is unlocked/unlatched and you can just pull on the door to open it. When the panic device is not dogged, it is latched and you need an active trim (like a lever) or a key to retract the latch(es) and open the door. In either case, free egress is achieved at any time by pushing on the touchpad or crossbar of the panic device.
Doors Gone Wrong
This is one of those openings that makes me cringe...yuck! But I can't let a teachable moment go by. Yesterday I got a call from an architect who asked whether it was acceptable to put a panic device on one leaf of a pair when only that leaf is required for egress width. The codes aren't 100% clear on this, but I have had code officials require panics on both leaves of a pair even if only one leaf is required for egress. You also need to consider the alternative to using panics on both leaves...a panic on one leaf and auto flush bolts on the other. This application also requires a coordinator and overall it's a problematic application.
How It All Began
This article was written by Carl Prinzler, one of the creators of the original exit device, at the end of the 1930's. I think it's an interesting insight into the development of the first exit device and the code requirements at that time.
Blumcraft Center Housing
I am running into more and more all-glass doors on my projects, and in the words of one of the contractors I'm working with, "Doors are being asked to do things they've never done before." I've had large glass panels pivoting at the center, glass doors acting as opening protectives in fire-rated walls, and glass doors with all types of electrified hardware applications - all with invisible wires, of course. Given the limited options available for glass door hardware, it's often a real challenge to specify hardware that meets the functional and aesthetic requirements for the project. On one project I specified Schlage mortise locks installed in Blumcraft center housings and it was a great solution. The glass door manufacturer had no problem accommodating them, the architect was happy with the way they looked, and I had the full range of lock functions to choose from.
New Requirements for Nightclubs in Massachusetts
In the Good Old Days when I was a more frequent nightclub visitor, I remember trying to exit through a club's main entrance at closing time and encountering a locked door. The manager had locked the door to prevent more people from coming in. The vestibule was dark, and the dark bronze storefront door had an Adams Rite deadlatch with a dark bronze lever. The lever was completely invisible and people started to gather behind me. If it had been a panic situation there could have been tragic consequences.
Panic Hardware on Electrical Rooms
Beginning with the 2002 edition, the National Electric Code (NFPA 70) requires that certain types of electric rooms have doors that open in the direction of egress and are "equipped with panic bars, pressure plates, or other devices that are normally latched but open under simple pressure." According to an engineer I spoke with at the National Fire Protection Association, the releasing device could be a hospital latch or paddle-type release, but the fact that the words "panic bar" are used in the Code has prompted many code officials to require panic hardware.
