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)

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.  🙂

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 […]

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 […]

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.  […]

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…

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…
