Video Transcript for Review of Marlboro Trailer Door Hinges - Barrel Hinge - MA34ZR

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 will provide a nice sturdy, continuous support along the length of your cabinet, door, or panel. It's great for oversized doors, trailer doors, and entrance doors. And it'll provide more support than multiple small hinges.

This is a nice continuous design that'll reduce the stress on the hinge with heavier doors. And this does rotate 270 degrees. Let me just zoom in so you can see that. You can see the hinge, it'll go 270 degrees for nice full opening and closing motion. This is made of a durable stainless steel construction that'll resist corrosion.

And this has a 2B mill finish, which gives the metal a bright shine. And when they say 2B mill, what they're saying is it's a standard finish that has a smooth, bright and moderately reflective, and may even exhibit a slight luster to it. It is a weld-on or bolt-on installation. Now, to bolt it on, it will require drilling holes into the hinge. This part is made in the USA.

Last thing I wanna do is give you some dimensions on this. We're gonna zoom back out to give you the length. And the length, we'll measure all the way from one end to the other end, it's right at 72 inches. The width on it, which will be the open width. Let's just zoom in for that one.

So, if I have this open all the way, the opened width, you can see it's gonna be right at three inches. The knuckle length, each one of these little sections is considered a knuckle. So, the knuckle length on this is gonna be right at one inch. And then the pin that goes through that piano hinge is a quarter inch diameter. But that should do it for the review on this 72 inch long, three inch wide stainless steel piano hinge..

Stainless piano hinge isn’t stainless and has almost rusted shut . Would not send a replacement unless I removed and returned the original which had been cut , drilled, and installed
