Video Transcript for Review of Marlboro Trailer Door Hinges - Barrel Hinge - MA94ZR

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..

Correct item received, but tape gum on the hinge will require extensive cleaning before use. Was not necessary to be taped up, Or use painters tape the is easily removable leaving no film.

I have ordered a number of products from E trailer. All were very good. They have excellent customer service and I would buy from them again. One little thing they could use help on is packaging their products so they don’t fall apart on the way to the customer.

Review from a similar Marlboro Continuous Hinge in Trailer Door Hinges


Wrong item shipped, received 3” wide STEEL, not 4” wide ALUMINUM. I was forced to wait for the second item because it wasn’t in stock, now I’m waiting again, and having to return one item to UPS before the correct item is sent out. Please check stock and ensure it is the correct item

This piano hinge is very well made. It is a heavy duty hinge that will probably out last the job box I am putting it on. I will keep etrailer in mind for future projects.

This hinge is heavy duty. We have had no issues with the door sense installing. If in need to get rid of hinges that keep getting bent, this might be the hinge you are looking for to do the job.

Good and sturdy. Easy to cut to length - just watch for rod in the middle sliding.
Appears to have taken the black rustoleum spray paint well.
