Video Transcript for Review of the 3" Wide Continuous Hinge

Hi there, I'm Michael with etrailer.com. Today, we're gonna take a quick look at the 7-foot-wide by 3-inch-wide continuous steel hinge. This is a piano hinge that's gonna provide a sturdy, consistent support for your door or tailgate on your utility trailer. The continuous design is gonna offer more support than your smaller individual hinges and it's gonna help reduce the stress on your heavier doors. Now, this is 7 feet wide by, or 7 feet long by 3 inches wide, you can see if I get this to stand up properly, it's about 3 inches wide. It is going to have the two sides that will each fold in, does have 270 degrees of rotation for your full opening and closing, so it'll give you plenty of adjustability there so that you can open your door properly.

Each side of the hinge is about 1 1/2 inches in width there, so combined for that 3 inches. This is a 16-gauge steel construction, so it is gonna be very durable and long lasting. You can either weld this on or bolt it on. It is a solid metal, so there's no pre-drilled holes. So you can drill out your own holes to match your setup.

Our individual knuckle links here, we're looking at right at 2 inches and our pin diameter is 3/8 of an inch. This is made here in the USA, so you can trust it's made to the high quality standards that we've come to know and trust for products that are made here in the U.S. So if you are needing a 7-foot-long by 3-inch-wide continuous hinge, this is gonna be a great option for you. That completes our look for today. Again, I'm Michael with etrailer.com.

Thanks for watching..

used two of these to make lid for my trailer work very well and function well in all kinds of weather



by:

Heavy duty and well made. Just what I was looking for.

I am very pleased with the products i purchased from etrailer. Very fast shipping and spot on descriptions of all the items purchased. If only all online products could be described as detailed. Any questions i had where answered either by phone or email. Thank you you so much for the great products. One stop shopping made it easy to build my off road camper. A few things purchased where the timberen hd 3500 lb axles 4 in lift with 10" breaks, marker lights,tail lights,and some interior lights as well as the trailer wiring and all the connection that go with it. . And the red arc off road trailer break kit. Thanks again.

It all worked as I had intended, although I suppose it would have helped to have pre-drilled countersunk screw holes on the flanges. . .but I guess welding these in place is common.
My old hinge was seriously rusted, but of course the factory welds still held. So after cutting and grinding, I got the door free, drilled some screw (and bolts on one side) holes.
Aligning is always a problem when the hinge flange is hidden when closed. I experimented with blocking the door into the correct position, guessed a little on some screw locations and finally settled on what might work.
Although I have bolt heads visible on the outside, the door works. That's what counts. It is after all a horse trailer! . .

All in all this has been a good product. Don't know why, but it has a tendency to rust if you don't keep oil on it. Does what I bought it for.
