Sure, why not be a little self-centered. Well, that is if you happen to be a Guden self-centering damper! This product’s beautiful internal springs and quintessential tube-in-tube design allow for a flawless 1.20″ movement of the rod in both compression and extension. Then when the external force is removed, the unit miraculously self-centers back to it’s original at-rest position of 8.80″ C to C. Of course all this splendid back-and-forth motion is expertly dampened for a smooth extension and compression. These gorgeous self-centering dampers are currently available in a wonderful 9 lb or a fantastic 12 lb version and have special swivel socket ends and ball studs already installed for a completely perfect quick and easy mounting. Yup, definitely sounds a little self-centered to me.
At first I just noticed the weld-on’s on this Alaskan tour boat, but then being the Hinge Whispering kind of guy I am, I got down closer to look at them while everyone else was on the other side of the boat taking pictures of some big mountain or ice formation or something. The weld-on was totally painted over, and I couldn’t scrape enough paint off the hinge to try to figure out what metal it was made from, but the grease fitting nub on the top point of the hinge made this hinge sighting very special. The use of this grease fitting weld-on is obviously for lubrication which may be needed on heavily salty corrosion type days. And luckily while some glacier calving (when a glacier piece breaks off into the ocean) was distracting the other passengers, i got some additional time to see more of this pair of hinges or I might have missed the most interesting thing to see about them. Whomever welded this door on disregarded the first rule of slip hinges! Look how the bottom half of the top weld-on and then the top half of the bottom weld-on are welded to the door instead of both tops or both bottoms being attached to the same side. A very difficult way to weld these hinge to the door and frame but it insures that the the door isn’t able to be slipped off and removed unless the hinge welds are broken. So I assume that they must not have wanted to be using this hinge as a lift off, but more because of it’s grease fitting lubrication abilities. Or maybe it was just a cold day in Anchorage and someone rushed welding this hinge on. Who knows for sure, but it’s certainly interesting and a very exciting Alaskan sighting! Ok, ok I guess I’ll go back to looking at the glaciers….
When specifying a handle, one of the most important dimensions is the C-to-C or center-to-center dimension for the mounting holes. You will measure this dimension just like it sounds, from the center of one hole, to the center of the next hole, assuming the handle only has two mounting holes. Some handles may have 2 holes on each handle leg, but I’d say most of this type that I’ve seen had each set of holes in line with each other, so the C-to-C dimension would still be the same for each pair of mounting holes. It won’t matter what the hole size is, you just need to measure from the center of it. In the handle world, most C-to-C dimensions are probably in full inches or half inches, or possibly in full millimeters or centimeters, but of course, depending on the design engineer, any dimension can occur. Custom C-to-C dimensions can always be supplied, but keep in mind, a 3.00″ or 3.50″ C-to-C handle is most likely going to be less expensive and easier to find than say one that is 3.80″ or 4.15″ C-to-C.
Coatings on hinges are just one way to make your hinge more corrosion resistant, or just to make it blend in with the chassis it’s mounted to. Check out this black powder coated hinge above. You can barely see it against the black painted frame, and I almost missed seeing it after prying open the back fuse panel door on this large electrical box underneath an unused store checkout counter. Except for the unusual usage of zinc plated screws, this hinge seems to almost disappear into the black frame. Why they didn’t use black screws, I’m really not sure. But if they had, maybe this hinge might have gone unnoticed. Black zinc plating or a black powder painting are two simple ways to get a black finish on steel, or for a less costly, but less beautiful finish, black oxide can also be done. If the material is stainless, you can do a black passivate, or of course, a painted finish as well. But one thing to note on finishes other than painting, black finishes, especially black tinted plating, can tend to be a little more costly as the EPA has gotten tougher these days, and disposal of these color finishes is getting more difficult.
Ball studs are just one type of hardware that help attach a gas spring to the door or lid and to the frame or chassis of the product they’re mounted to. You would use them with plastic socket end fittings or, as shown, metal socket end fittings. They are available in either an 8mm or 10mm ball diameter, several different thread lengths, and in metric or US thread sizes. Guden also carries them in both zinc plated steel and in stainless steel. Custom sizes can be done, but hopefully one of our wide array of choices will fit your application as custom requests will require a significant quantity to make them cost effective.
While the majority of Guden products are Made In USA, to keep our selection as well rounded as possible, we also import products from several different countries. All countries of origin are clearly marked on our boxes and paperwork, and if you require additional documentation of a parts origin please, we can quickly and easily complete your submitted forms. I know, I know, you hate all this just as much as we do, but until regulations are different, which doesn’t seem likely, we’re all stuck with doing it. We’ve constantly working with our suppliers to get the most current and accurate information and we always want to make it as quick and painless of a process for everyone involved, including us!
PITCH – This term isn’t used all that often anymore, but it does come up every once in a while, so an explanation of what it is certainly can’t hurt. Pitch is the measurement from a point on a knuckle to the same exact point on the next knuckle falling on that same leaf. As in the picture above, measuring from the right end of the knuckle, to the next right end of the knuckle. It’s almost just adding two knuckle lengths together, but you also need to add in the spacing between the knuckles, so this measurement includes those two spaces as well.
This special hinge sighting was so rare and unique, it took a trip across the border to Toronto Canada for this hinge whisperer to capture it! The elusive Embossed Spring Leg Hinge is a very very rare variety, and even rarer to be able to see it in use on the outside surface of the hinge. For most spring legs, the spring just lays on the leaf, but adding an emboss into the hinge leaf, the channel allows the spring leg to be flush with the surface, so nothing catches on it. Or most commonly you emboss so that you can mount that surface of the leaf flat against another surface. It was wonderful to spy this in a Toronto taxicab and I couldn’t wait to post this special find.
In observance of the Fourth of July holiday, the H.A Guden Co. will be closed July 4th and July 5th. Enjoy your holiday, and be safe with those fireworks! If you should need product information or pricing, please visit our website and we will reopen on Monday July 8th.
With so much talk about equal this, and equal that in the national news, what better time for a talk on Equal End Knuckles for hinges! Depending on the length of your hinge, you may be getting a partial knuckle situation and to make the hinge look more symmetrical, we can supply the hinge with balanced or equal end knuckles as pictured above. The process of doing equal knuckles on the ends is also handy when you have very short hinges, and need to meet the minimum 3 knuckle construction for a well operating hinge. So if the knuckle length is say .50″, and you want to have a 1.00″ long hinge, you could have one center knuckle of .50″ and equal balanced knuckles of .25″ . Who says hinges don’t have equal rights too. :)
