Hinges & Pivots

Hinge Fillers

What you’re looking at is an existing fire rated frame with a new door that I saw recently during a fire door inspection.  Most of the other doors that I inspected that day had steel hinge fillers to fill the existing hinge preps before the continuous hinges were installed.  So why were a half-dozen or […]

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 […]

W Hotel, Boston

I recently went to Boston’s Theatre District to see the W Hotel, a project that I wrote the hardware spec for a few years ago.  The opening date for the hotel is October 22nd, with the condos on the upper floors to follow.  The architectural firm is one I’ve worked with many times – TRO/Jung Brannen.   Whenever I’ve mentioned this […]

A Pair and a Half = 3

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 […]

Too Many Pivots

I was walking down the street the other day, and I noticed that all of the entrance doors on the building I was passing had A LOT of intermediate pivots.  I didn’t have much time to investigate, but I took a picture in case I decided to do a blog post about it someday.  Well, […]

Spring Hinges

After my post about the Parkside West fire, a couple of people have asked me what I have against spring hinges.  I’m not one to discriminate against hardware of any function, style, or finish, but I also like things to do what they’re supposed to do.  If I could get my kids to act more […]

Olive Knuckle / Paumelle Hinges

I haven’t thought much about these since I was in DHI school (a really long time ago), but today I saw two types of paumelle hinges along with some olive knuckle hinges in the same facility.  Beautiful hinges, but a very tough door and frame prep.

Piano Storage

Last night’s CSI meeting was a tour of the recently-completed Shalin Liu Performance Center in Rockport, Massachusetts.  It was kind of a hike especially with the threat of traffic problems, but I thought I might be able to get some good door pictures. I’m so glad I went!  There were some really interesting door applications, […]

Curved Doors

Here’s another door from the Shalin Liu Performance Center in Rockport, Massachusetts.  It’s actually a curved door from the existing building attached to a new door.  Because of the thickness of the two doors, wide throw hinges were used.  Wide throw hinges are typically used when more clearance is required behind the door when open […]

Top Hinge Retrospective

We’re back from our vacation, but I have some more photos to share before I finish up this unplanned series on hotel doors.  As I mentioned in an earlier post, our hotel was a series of buildings connected by propped open, non-latching, damaged doors which were originally fire rated (as indicated by the painted labels).  […]

Square Edge vs. Beveled Edge

I was reading an article about blogging in Inc. the other day, and one paragraph really resonated with me: “The thing most people don’t understand is that the difference between a blog post and a magazine article is the difference between conversation and presentation,” notes Strauss. “If I were giving a presentation on a stage […]

Now you’re really in trouble.

I love photography and I’ve always wanted to learn how to use all the fancy buttons and dials on my camera.  My “big” camera (a Canon T1i) takes great photos but I knew it could do so much more if I only knew what all those settings meant.  Well, today I finally took a class.  […]

WW: Hollow Metal Doors (Literally)

I saw both of these doors today, in two different facilities.  Yes, they are both fire rated.  One is a cross-corridor pair and one is a stair door. You need to login or register to bookmark/favorite this content.

E.R. Butler & Co.

I’ve been in the door and hardware business for a long time – almost 25 years.  While I’m still passionate about the products, the industry, and our customers, there are some days when I’m not quite as excited as I once was.  It’s kind of like the old, “I love you but I’m not in […]

WW: Big Butts

Is it me, or are those some really big butts on pretty small doors?  This post should bring in some interesting stats…like the guy who Googled “naked ladies with no cover-ups” and was sent to my blog post on naked closers with snap-on covers.  🙂 You need to login or register to bookmark/favorite this content.

Lexington, Virginia

We only spent a brief segment of our road trip in Lexington, but it was long enough to spot a couple of doors of interest.  Our hotel was originally a single family residence and it’s on the Register of Historic Places.  We checked in pretty late at night but I immediately noticed the mess they […]

Back-2-Basics: Hinge Types and Applications

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 […]

Fire Door Brain Teaser

Paul Goldense of Goldense Building Products showed me this pair of fire-rated doors last week.  He mentioned that the architect had to change the arch to make it a “flatter” curve because of the rating, and that they had to use continuous hinges instead of butt hinges.  Who can tell me why? UPDATE: You guys […]

Reader Photos

It warms my heart when someone says, “I saw this door and I thought of you.”  🙂  That’s what Angie Sutton of Ingersoll Rand Security Technologies wrote when she sent me this photo of an old vault door on a storage room at the county courthouse: Travis Willis of American Direct sent this photo of […]

Doors of Indiana

I coincidentally received these two sets of photos on the same day.  Who knew there was such cool hardware in Indiana?? These are from Mary Hinton of Mulhaupt’s.  I’ve never seen hinges like these.  Have you? And from Cory Yamaguchi of Ingersoll Rand Security Technologies, amazing pulls on art gallery doors.  Thanks to both of […]

WWYD: A Little Help Here?

Today is the 3rd anniversary of iDigHardware (aka iHateHardware)!  WOOHOOOO!!! If you were wondering what to send as an anniversary gift, all I want is your experience and expertise.  I have had several questions lately that I could use your help with.  I am always amazed by your willingness to add your two cents to […]

WW: Unhinged

I’d like to tell you where I got these photos but then I’d have to kill you and that would be bad for business.  😀 They are posted with permission from someone who’s spending A LOT of time looking at fire doors lately. And yes, these are fire doors: And in case you’re not sure […]

Q&A: Continuous Hinge Retrofit

Question:  I have a hollow metal fire door that is sagging due to failure of the top hinge reinforcement.  Is it acceptable to remove the butt hinges and install a continuous hinge on the existing door and frame? Answer:  NFPA 80 does not specifically address this application, so it would be dependent on what is […]

WW: Manufacturer’s Standard Fasteners

This photo of a hospital corridor door was sent by Hyun Myung Kang.  I’m pretty sure this installation doesn’t comply with NFPA 80.  You need to login or register to bookmark/favorite this content.

New York City – Part 2

Here are some more photos from my weekend in NYC…these are all about taking a closer look. When I was looking back through my photos I couldn’t figure out why I thought this pair was interesting.  Until I looked at the close-up.  Now I can’t look at either photo without seeing the giant piece of […]

WWYD: Help Wanted

I answer A LOT of questions every day, and I love doing it.  I’m so glad to be able to provide this resource for our staff and customers, and anyone else who comes across my site.  But sometimes I get questions that I don’t have a good answer for, and that’s where you come in.  […]

Reader Photos

Thank you to everyone who has sent me photos of doors they’ve seen in their travels (or while laying on the couch).  Kelly Chimilar from Allmar Inc. noticed these doors with an obvious egress problem while watching Thursday Night Football.  If you don’t know what the problem is, I will hold a special online study […]

More Doors of Nashville

A hodge-podge of the doors I saw while I was in Nashville for CONSTRUCT last week… The West End United Methodist Church: Beautiful bronze doors on the Freemasons’ building:   The Customs House: The Lutheran Church: The Barbershop Harmony Society at night: The War Memorial bronze gates – also at night: A creative hold-open: Are […]

Doors of River Street – Savannah, Georgia

Before anyone says, “Why didn’t you stop and see me??”, we were only in Savannah for a quick lunch break.  🙂 Here are some interesting doors from the River Street vicinity… I saw this door and thought – “Cool!  Half-surface hinges!”  Ok – that makes me sound like a weirdo but that’s really what I thought.  […]

FF: Dutch Door Hinge

From Stephen Richardson and Joe Beeman of Allegion, here’s a hinge modification they saw recently.  Would you consider this acceptable?  Why / why not? You need to login or register to bookmark/favorite this content.

Art Institute Fire Doors

These are 3-hour fire doors which divide the modern wing of the museum from the older wings. This is an award-winning museum which houses more than 300,000 works of art in its priceless collection. The chance of a fire may seem unlikely, but if a fire occurs, the wedged-open fire doors will not protect the rest of the museum…

WWYD? Hanging Aluminum Storefront Doors

What is your preferred method for hanging an aluminum storefront door, and why? What are the considerations – aesthetics, function, durability…others?…

TBT: Wide Throw Hinge

These photos were sent in by Eyal Bedrik of Entry Systems Ltd., after his recent trip to the US from Israel.  The photos were taken at the George Eastman House in Rochester, New York.  The home was built between 1902 and 1905, and is 35,000 square feet with 50 rooms! There is sometimes confusion between […]

FF: Custom Wide Throw Hinges

Check out this Fixed-it Friday photo of a creative hinge modification, sent in by Andy Armstrong of BR Johnson. At least it doesn’t appear to be a fire door…

Cease Fire Door Hinge

As most of you know, I love to see creativity and innovation within the door and hardware industry, especially if it helps to increase fire prevention and life safety. I received a video this morning, introducing a product that has been developed by two retired FDNY firefighters. It is a spring hinge with a fusible link, so in normal operation it acts as a typical hinge but when exposed to heat it closes the door…

FF: Hinge Pin Stop

I have not yet seen this product (the DoorSaver II) in use, but I’ve definitely seen distributors enlarging the hole in a residential hinge pin stop in order to use it on a commercial hinge. This looks like an interesting idea…

Maneuvering Clearance with Spring Hinges

A question hit my inbox a few weeks ago that I had never considered before: Does a door with spring hinges require the same maneuvering clearance as a door with a door closer?

FF: Multicultural Madness

When I stopped for a snack yesterday, I didn’t expect to be called into service on a defective door that was threatening to crush someone while simultaneously preventing egress. The fun never stops…

Intro to Ives Hinges (video)

One more whiteboard animation in the latest series…this time on hinges!

More Reader Photos

Austin Baumann of Central Indiana Hardware sent me this photo of the emergency exit in a mirror maze. This would be considered a special amusement building – I wrote about some of the requirements for those occupancies here. I have often seen means of egress modifications…

WW: Abuse and Neglect

Today’s Wordless Wednesday photo was sent by Nolan Thrope of Allegion…this is a cross-corridor fire door in a school. The closer is missing as well as the obvious hinge problem. Sadly, this type of neglect is not uncommon. 🙁

Fire Door Clearance / Continuous Hinge

Two paragraphs were added in the 2013 edition of NFPA 80 to address continuous hinges used on fire doors. I’ve seen these sections many times and never noticed a potential problem, until it came up twice in the last couple of weeks…

FF: Pivot Problem

A reader from Armor Lock & Security sent me the first photo a couple of months ago. They had been called to a convenience store to work on the safe, and noticed that the top pivot on the front door was barely hanging on…

Decoded: NFPA 80 Requirements for Hinges, Pivots, and Continuous Hinges (September 2016)

With the continued focus on fire door assemblies, it’s important to be familiar with the basic requirements as well as what has changed in the more recent codes and standards. This article focuses on hinge requirements for fire doors…

Intro to Continuous Hinges (video)

Here’s another of our latest set of whiteboard animation videos – taking it back to basics and discussing continuous hinges. If you know someone who is learning about hardware and could benefit from these “intro” videos, please share a link with them!

FF: Don’t Talk to Me About Fear

Maybe this is cracking me up because it’s the middle of the night…I guess we’ll see if it’s still funny in the morning.

FF: Unhinged

From these photos it looks like the holes for the hinge screws were stripped, so the wrap was added – but that doesn’t add a whole lot of strength to the installation.

WW: Hinge-Hasp

Thank you to Curtis Meskus for these Wordless Wednesday photos.  This pair leads to a storage room in a motel.  I have a feeling these will show up in one of my nightmares sometime soon.   You need to login or register to bookmark/favorite this content.

FF: DIY Swing-Clear Hinges

Michael Wallick of Kelley Brothers sent today’s Fixed-it Friday photos of a DIY application he spotted at a hotel. I think this is the first time I’ve ever seen swing-clear hinges that appear to have been fabricated on-site…

WWYD? How should these doors be hung?

This is a good one! What would you use to hang these doors, and what type of door closer could be used?

FF: Falling Off

What do you think the wood strapping is for?

FF: Pocket Pivots

If you can prove to me that you were the detailer for this project (or otherwise responsible for the details), I’ll send you something from the iDigHardware prize vault!

Pocket Pivot Follow-Up

After last Friday’s post about pocket doors, several people asked for more information about this application. Here are the answers to some frequently asked questions…

WW: Hotel Hinges

Considering the liability a hotel could face if their fire door assemblies failed to perform during a fire, the repair methods employed by many hotels seem pretty irresponsible.

QQ: Hinges for Fire Door Assemblies

Quick Question: Are steel, ball-bearing, butt hinges for fire door assemblies required to be UL listed?

QQ/WWYD?: Old Fire Doors With 2 Hinges

Is an existing fire door assembly with 2 hinges acceptable, or should it be noted as a deficiency during a fire door inspection?

FF: Wheelie

I have a theory about what happened here…what’s yours? This “fix” shows the importance of making sure the correct hardware is specified from the get-go.
