@TechConnectify I love to hear about undercontemplated yet ubiquitous doohickeys!

socks

@TechConnectify Time to develop a new obsession over something I've previously taken for granted

Panegyr 🤡🎪

@socks @TechConnectify felt. I definitely started using boxed detergent in the dishwasher after those videos came out

It’s both cheaper /and/ more effective

Michael Gemar

@TechConnectify Terrific as always — I had no idea how these work, or that they were adjustable!

Kacper Potoczny

@TechConnectify it's funny, that any of your videos can be announced like that, and still every of them is different and interesting as hell! Good job!

Xer Shadow Tail ☄️🌺🏳️‍⚧️

@TechConnectify These things are great, I have a basic one on my front door and took awhile to adjust it when I installed it months ago but I wish it had two speeds to it instead of just one.

Aroop Roelofs :verified:

@TechConnectify Had to readjust a bunch of them during internship.

So nice and quiet.

Juneau

@TechConnectify I figured enough out about these in the last year to fix a couple doors that were being super annoying! A door that properly closes is so satisfying!

Dawn

@TechConnectify I need a warehouse for two of them as well, possibly even three of them

cmdrSprocket

@TechConnectify this is why we need an obsessive nerd! 😁

(Any idea about international variations?)

Robin Daugherty

@cmdrSprocket @TechConnectify I can speak about some European ones. I can definitely say that they don’t label them with the same letters as in the video. ;)

Other than that, the ones I adjusted in my office are extremely similar. But there is one detail that I’m assuming was cut from the video for time: the 15-degree latching-speed position is adjustable in many cases. In my case the swing arm was shortened/lengthened by turning it.

I look forward to the deep-dive video about door closers!

@TechConnectify a)…, and

Wilbur

@Elephant @TechConnectify I just saw this in the captions as i was reading this lmao

Bjørnar 🇧🇻

@TechConnectify Cool! Saw a few videos recently on constant force gas springs. Looking forward to additional learning on these doohickeys!

Merovius

@TechConnectify Every since our house got rid of it recently, I think about it all the time… With some nostalgia 😔

gudenau

@TechConnectify This Old Tony just did stuff about gas springs, interesting timing.

Ryan

@TechConnectify
Love this.

It's funny, I live in an old mill, and the old fire doors are still hung up for decoration.

They're basically big doors that sit on a diagonal rail with a release mechanism. In the event of a fire, somebody fleeing is supposed to knock it off the catch, causing it to roll into place in front of the doorway

Dec.tar.bz2

@aer
If properly installed, they are also self-closing in case of fire.
They have a cable or chain holding the door open, with a fusible section that melts when there's a fire nearby.

Ryan

@dec23k Oh awesome, yeah that makes sense. I'm sure they're not properly installed, haha. At this point they're purely decorative, with modern fire doors in their place.

Danny Blue

@TechConnectify how do you even notice these things enough to start researching them?!

kroimon

@TechConnectify I feel like @deviantollam could tell you if a fire door is still a fire door without latching hardware 😄 I hope y'all watched his great talk about fire code: youtu.be/CtHpiNBzPsk

Deviant Ollam

@kroimon @TechConnectify yes, he mentioned that talk in his latest video and links to it in the doobly-doo

kroimon

@deviantollam @TechConnectify I should really finish watching a video and check it's comments and description before commenting myself, but for some weird reason, the topic excited me to much 😅

Nick Heer

@TechConnectify Great video as always, and you reminded me I need to fix the spring hinge on my garage-to-house door.

Stupid story: when I was in high school, we had some fire doors with electromagnetic door holder-opener-thingies in a long hallway similar to that school footage you used, and a breaker panel at one end that was never locked. A fun game which I “heard about” was sitting by the panel and flipping the dedicated breaker just as someone approached those doors, slamming them in someone’s path.

Daniel Morris -✌️🇺🇦

@TechConnectify This is the video I didn't know I needed... Thank you!

gudenau

@TechConnectify Did you goof the captions at the end of the video or is this a YouTube issue?

Technology Connections

@gudenau uhh... that's just an oops on my part. I'll fix it

C_Chell

@TechConnectify I really like your videos. You are one of the few youtubers I know to keep me viewing their whole videos even if the subject seems to be mundane.

joop

@TechConnectify you said something like "you can even adjust these so the swing speed is faster than the latch speed. although I don't think there's much reason to do it like that" and I'd here to tell you I love doors like that! Keep the draft out, but no noise when closing = perfection!

Also also i'm here to tell you I think about these often, but have never bothered to look up how they more, so i'm v thankful for you making this video!

And you described the vestibule acting like a sluice of sorts as a concept, but I've seen them! I think the hospital here has them as a compromise between accessibility and heating.

TransitBiker

@TechConnectify Now I’m curious about automatic doors. I remember when they had the framed plastic mats to trigger the doors, then slowly most places have changed over to the IR sensors - which i assume work similarly to the alarm motion sensors? I also remember some places had the plastic mats flush to the floor/exterior sidewalk, while others had a clearly raised frame.

TransitBiker

@michaelgemar yeah I saw that one too. I’m more interested & curious about the plastic mats that used to be in front of automatic door as years ago and still are in some places.

Josef

@TechConnectify Thanks, now my interest is sparked and now I need to look up how a double door can be linked up.

Somehow one side is held open until the other is nearly closed, so the latch in the correct order.🤔

Felix 𝄢

@fesoj @TechConnectify most times I see this configuration in Germany there’s a piece hanging on the wall above the middle of the doors that will hold the door that needs to close last open until the door that needs to close first pushes it up…

rallias

@TechConnectify take pictures of the Aurora! I would imagine you get an excellent view of it in your kitchen!

Zach (Ela) - TechnicalOtter

@TechConnectify Damn thanks for educating me on this one! Super useful and now I guess I'm writing a polite e-mail to the building manager at work...

Technology Connections

@technicalotter I sense a great disturbance in the facilities managers force...

InsertUser

@TechConnectify

I think I've only ever seen Americans mention the electromagnet-on-a-wall type of device for holding open fire doors.

Are you allowed the type that screw to the door and push a peg into the ground over there? They're meant to let go if they hear the alarm.

screwfix.com/p/dorgard-ll800-h

Andreas Sikkema

@InsertUser Looking at your posts it appears that you’re in/from Belgium? Your neighbors to the north have the electro magnets everywhere in institutional buildings (government, hospitals etc)

InsertUser

@bix

Nope. Hence having to use Google translate.

I'm not saying I've never seen the electromagnet version. I've just never seen Americans mention the other option.

Ceri :neofox_nom_verified:

@InsertUser@en.osm.town @TechConnectify@mas.to They have them in europe(well the UK at-least which i count as Europe) my parents church has a few as part of their fire system, and you can still get them from trade stores

Bruno Girin

@TechConnectify nice! I remember a French song in the 80s that was about those and a good part of the video showed one of those at work.

Semitones

@brunogirin Do you remember the name of the song by chance?

Bruno Girin

@semitones no and I'm now thinking it might have been an advert, maybe for a company called groom. I only remember a guy with a mullet singing "ne fermez pas la porte, le groom la fermera", cut to shot of door closer pushing a door closed.

Sonny Bernardo

@TechConnectify “Fire, it turns out, is bad” is a great line :)

Paul Martin

@TechConnectify Excellent from its opening to the smooth closing, with a little oomph at the end.

fbn

@TechConnectify
In school we had a lot fun adjusting those door closers especially the opening resistance so that some of our teachers had quite a strugle to get in to our classroom. From todays view we created a real safety issue 😥

Wouter

@TechConnectify Wait, you can change the speed on these things. Why didn't I know that?

Justin Azoff

@TechConnectify I need to get a new one of those for my front door, but I didn't know what they were called at first.. I was quite surprised when I put "What are those door closing things that make doors close slowly called?" Into google, and found that they were in fact called "door closers".

Jake Cripps

@TechConnectify man, I had to fix several of those when I worked at a bookstore.

Michael K Johnson

@TechConnectify This video is awesome and now I want to replace my spring hinges!

J. Steven York

@TechConnectify
I'm a long-time fan, but i appreciate your posts here. The reality of YouTube these days is that its easy to miss a video, or even lose an entire channel, until you finally think, "Whatever happened to them." The reminders help. Keep up the great work. Always amazed at the common but obscure tech you can find and make fascinating.

Kevin Bowrin ☕

@TechConnectify the fireplace joke really got me, great work

endrift

@TechConnectify wild, I was just thinking about these a few days ago. That said, I looked up how they worked years ago because I'm the exception in this case.

Jonas Trostle

@TechConnectify now I want to add one to every door in my house.

Even the cupboard doors

Hanneke 🐣

@TechConnectify another excellent video as always. Love how passionate you are about mundane things and show us how interesting they really are.

Regarding your comment on vestibules, I found it very surprising that you mentioned never seeing ones where the doors don’t open at the same time. Especially as I gather that you get pretty cold winters there! Here (NL, with very mild winters these days) I wouldn’t say they are a common occurrence, but they do exist and they are usually set up to behave like that in winter and not in warmer months exactly like you suggested. I don’t often see vestibules in the first place though. High traffic areas like shops just have massive heaters above the doors which blast down hot air, or there are revolving doors. Those usually have three or two compartments though, this seems almost unworthy of mention but since you specifically mentioned four you might not see those often? Idk the world is a varied place sometimes!

logBoy

@TechConnectify oh my! They recently changed one of these in my building but did not change the default. Time to get the allen wrench out.

Funkster

@TechConnectify I watched and enjoyed the video that you made thank you

BrokenFlows

@TechConnectify this could lead to a real quality of life improvement…

Update:
While I’m still watching thre rest of the video, the first few minutes will definitely lead to quieter hallways in my apartment building. Thank you!

Torin Darkflight ΘΔ

@TechConnectify having watched this video on my lunch break, I'm now at the front counter at work, periodically looking at the door closers on the front doors, wishing I could adjust them so the right door stops slamming...if only the owner of the building hadn't permanently epoxied the cover shut to keep it from falling off. :p

delolzer

@TechConnectify I put my very small pp on the door closer hihi 😊

Varx

@TechConnectify Ogilvie station/Accenture tower in Chicago has a vestibule "air lock" where one door closes and it forces you to wait like 15 seconds before it opens the next doors.

It's just as confusing as you would expect. I was pushing my toddler through in a stroller and thought we were stuck between the doors until a nice man yelled "just wait it'll open!" From the other side of the door.

Jim

@TechConnectify enqueued for this weekend -- exciting!!

Atz

@TechConnectify

> i made a video about a thing which is everywhere but nobody ever thinks about

That is exactly my favorite kind of video.

octesian

@TechConnectify they really are just called fireplaces 🤔
Why aren't sinks called waterplaces, or vents called airplaces?

Carighan Maconar

@TechConnectify This made me realize my landlord cheaped out on these and bought the flimsiest whimpiest ones they could get away with. 😑

Josh H

@TechConnectify hooray, another everyday item I've been able to ignore up until this point in my life but will now never be able to ignore again.

In all seriousness though, great video. I love learning little things like this. It always seems to come in handy eventually

Dek 👨‍🚀🐧🚀 (

@TechConnectify well, I'll never watch a door self-closing the same way ever again 😅

Kevin :soon: EMF

@TechConnectify thanks for this! I might have a fiddle with the door closer in this office, slams quite badly.

houtig

@TechConnectify well done on the video. You had a question about sliding doors, with two opening at the same time. These doors can be fitted with a "winter" setting where the doors wait on each other to open and close. Limiting the draft of cold air. Little cable between the two controllers. Most of the time this isn't done because it limits the amount of people getting through a door. People are impatient, it is a forgotten setting on the controller box above the ceiling.

Dukem10

@TechConnectify Loved the video! I work with this stuff so i enjoy people talking about them. Something I think might interest you are Balanced doors. They have an extra pivot point so they open easier and are largely unaffected by building pressures. I work for the company that invented them and it has turned me into a door nerd...

morri

@TechConnectify as mail and parcel deliverer i know the plight of badly adjusted doors.

Jacob

@TechConnectify just watched this video and it was great. I got up a couple of minutes in to check my door - time to adjust my door closer!

Felix Urbasik

@TechConnectify That was a great video. Even my wife liked it.

Oscelot

@TechConnectify Excellent video! I’d always wondered how they worked. Also thank you for doing the work of tackling hotel doors. Good gods those things make me jump.

Trek Glowacki

@TechConnectify wait I don't need to run away from my building's recycling closet, grimacing, with my hands over my ears?!

adorfer

@TechConnectify this content floats my boat and i would really appreciate a follow up into the rabbit hole of mounting those door closers... and the adjustment to the linkage length in case the latch-speed-valve does not kick in.
