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..

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!



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.



by:

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!

Work great. More sturdy than piano hinges on concession trailer.



by:

Very impressed with the quality this hinge. I had to repair my FlipBak tonneau cover. This hinge will provide superior security over the original piece of rubber that those tonneau covers use as a hinge.

Thanks for the excellent customer service.



by:

3 stars, due to packaging. Ordered 3 inch by 72 inch piano hinge. Packaging tube arrived without hinge, cap on end was missing.Went to post office to see if they seen it and they did. Brought it home and is in working condition.



by:

The hinge was perfect and was exactly what I needed. The customer service was second to none! They upgraded my regular ground shipping to 3 to 5 day at no additional charge. I wish the other companies I do business with had the customer service like etrailer.com does.



by:

It arrived on time perfectly protected with no damage. This was a last minute project that was dropped on me and I was scrambling to to find the components. etrailer was easy to scroll through and easy to complete my purchase.



by:

used cobalt drill bit drilled 4 holes in hinge on corners with paper to keep door space for future paint ,drilled holes in hinge only just touch wood ,undid 4 screws ,recessed wood with bur thing ,punched stainless hinge into wood, screwed in screws near flush ,very clean super price and strong ,thank you



by:

Very well constructed as we needed a heavy duty weld on hinge and this was the only hinge in the market to meet our application.
Fast service great feedback and properly packed for safe delivery as we live in an industry where what arrives and in what condition is always an unknown.
I highly recommend this vendor. I will be purchasing more products from their large selection.
2 thumbs up!!



by:

Just what I was looking for!
I plan
to hinge my shop stairs,pictured in the attached photo.



by:

This is the item I needed and it was sent out and received very fast, very pleased with the product here for my enclosed race trailer to help with my need after I had upgraded my trailer floors & ATP ramp door flap. Item was just as described in the video upon ordering off the website.

Thanks



by:

Everything is working as it should. Way better than the aluminum ones that where on thereForsure.



by:

Was very surprised with the quality of the hinge for the price. etrailer went above and beyond with packaging and shipping. Was worried that hinge would be bent in shipping because of it size but it was packed in a really strong tube. Product arrived 2 days before the estimated date. Will definitely be a repeat customer. I’m glad I stumbled upon etrailer and look forward to using them a lot more for my business. Thanks etrailer.



by:

Great product. Has held up great with no issues.

See what our Experts say about this Marlboro Trailer Door Hinges

  • 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.

  • 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.
