Video Transcript for A Closer Look at the 3" Wide Continuous Hinge

Hello, everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this 72-inch-long, three-inch-wide stainless steel piano hinge. Now this hinge'll provide a nice sturdy, continuous support along the length of your cabinet, your door, or your panel. And this is great for oversized doors, trailer doors, and entrance doors. It'll provide more support than multiple small hinges. And the nice thing on this hinge, it's a continuous design, which will reduce the stress on the hinge when it's used with heavier doors.

Now this hinge will rotate 270 degrees. We'll zoom in just to show you that. You can see, I can rotate this part. You lift us up here and you can see that it'll rotate back about 90 degrees. And then if you go forward, it'll go an extra 180 degrees.

So 270 degrees total rotation gives you a nice full opening and closing motion. Now this is made of a durable stainless steel construction, resists corrosion, has a 2B mill finish which gives the metal a bright shine. And that finish is a standard finish that's smooth, bright, moderately reflective, and it even may exhibit a slight luster. This is a weld on or bolt on installation. Now to bolt it on, it does require drilling holes into the hinge.

And this part is made in the USA. A few specs on this. We'll do the overall length. Take our tape measure, measure from one end all the way to the other end. Right at 72 inches or six feet.

And width on it, is gonna be the total open width, so the widest point. So if we measure that, you can see it's gonna be right at three inches. The knuckle length, each one of these sections here is a knuckle, so if we measure the length on those, a knuckle will measure right at two inches. And then the pin diameter of the large pin that goes through those knuckles, that holds both these pieces together, that size of that pin diameter's 3/8 of an inch. Again, you can see how it rotates. But that should do it for the review on the 72-inch-long by three-inch-wide stainless steel piano hinge..

See what our Experts say about this Marlboro Trailer Door Hinges

  • Availability Of 3" Wide 4' Long Aluminum Hinge With A 3/8" Pin
    It appears we do not carry a hinge that will fit those parameters exactly. We do offer a few 3" wide continuous hinges with a 3/8" pin like the # MA94ZR. This is a stainless steel hinge that measures 6' long overall. Unfortunately we do not offer anything in aluminum that will be 4' long. They will all be 6' or longer. So the # MA94ZR will be the closest thing that we offer.

  • Do Marlboro Continuous Hinges Come In 48" Or 96" Lengths
    The stainless steel options of the Marlboro hinges only come in 72" like the # MA94ZR. You could cut this down to 48" to make it work with your trailer though. There are 96" length options but they are both steel and come in 6" wide with a 1/2" pin diameter # MA32VR or 5" wide with a 3/8" pin diameter # PLR844.
