Video Transcript for 2" Wide Continuous Hinge Spec Review

Hello, everybody. This is Jeff at etrailer.com. Today, we're gonna take a look at this 72 inch long, two inch wide stainless steel piano hinge. Now, this hinge would provide sturdy, continuous support along the length of your cabinet, your door, or your panel. It's great for oversized doors, trailer doors, and entrance doors. And this will provide more support than multiple small hinges.

It is a nice continuous design, so it does reduce stress on the hinge when used with heavier doors. And this does rotate 270 degree, 270 degrees. Just want to zoom in and show you what we're talking about. So, you can see this part will fold back about 90 degrees. And then if you fold it the other way, it'll go about 180 degrees more.

So, it's about 270 degrees total revolution or rotation. Gives you a nice full opening and closing motion. And this is made of a durable stainless steel construction, which will resist corrosion. Does use a 2B mill finish, which gives the metal a bright shine. It's a standard finish that's nice, smooth, bright and moderately reflective, and may exhibit a slight luster.

Now, to install this in, it is a weld-on or bolt-on installation. Now, if you do bolt it on, it does require drilling holes into the hinge. This part is made in the USA. Few specs on this, we'll start with the overall length. So, we'll take our tape measure, go from one end, all the way to the other end, right at 72 inches or six feet.

The width on it when we have it all fully in, in the open position you can see, so the width, that position is gonna be right at two inches. And the knuckle length, each one of these partial portions here is called a knuckle. So, if we do the length of each knuckle is gonna be, you can see right at one inch. And the pin diameter, in other words, the long pin that goes through those knuckles that hold these two pieces together, diameter of that pin is gonna be right at a quarter of an inch. Again, you can see how it folds 270 degrees. But that should do it for the review on this 72 inch long by two inch wide stainless steel piano hinge..

Exactly what I needed for the ramp extension on my car trailer door/ramp. I couldn't find anything nearly as heavy-duty as this locally or elsewhere online. Thank you!



by:

I have 1 year of use as part of the upper ramp extension for my enclosed trailer and it has performed flawlessly. No rusting or corrosion and it has held up to traffic from a heavy diesel mower, appliances, and pallet jacks.

I tried ordering this same hinge through a hardware supplier and they couldn't get it. I found this on a web search and couldn't believe E-trailer had it in stock, it came within two days. Happy to get this project done!

Seems a fine product. These things look like they'll hold up the world...

Stainless steel piano hinge 3/8 pin 3 inch wide 6 feet long .120 thick weighing 13lb. Very sturdy/heavy duty piano hinge. I am happy with the purchase. I would have liked them to ha e a 4 inch option with the same specs as above. I think it would g8ve you more bight. I'm using this on a 5×5 epoxy laminated piece of 3/4 birch plywood which I will be using g this piano hinge to attach it to the transom of my sailboat as a flip up swim platform. Which will be subjected to about 800lbs at any given time. Iam confident this hinge will hold up. I will update review when I get it done and provide some pics if possible. Thank you ...I would recommend. Item as described.



by:

Just like promised! Six foot continuous hinge,not like what the competition sent me. Will definitely buy again.

  • Replacement Door Hinge For A 1992 Skyline Nomad Travel Trailer
    With your trailer being 30 years old most parts are discontinued at this point so a lot of troubleshooting and redneck engineering is going to be involved. The closest I can find to a 2" x 72" door hinge for your broken door would be the 2" Wide Continuous Hinge - 6' Long - 1/4" Pin Diameter # MA54ZR. If you're referring to a different part for your doors then please let me know.
