Video Transcript for Detailed Breakdown of the 4" Wide Continuous Hinge

Hi there, I'm Michael with etrailer.com. Today, we're going to take a quick look at this six-foot long by four inch wide continuous hinge. This hinge is gonna provide a sturdy, continuous support for your door or tailgate under utility trailer. It does have 270 degrees of rotation for full opening and closing motion. And that six foot length is going to offer more support than smaller individual hinges and it's goNNA help reduce the stress on your heavier doors. This can be welded on or bolted on.

As you see the side plates here are solid materials, so you can drill the holes wherever you need them to be. If you're wanting to bolt this in place, does have an aluminum construction. So it is going to be very lightweight and rustproof. Each side is going to measure two inches. Can show you that here with a little ruler.

So if I hold that up, you can see up to the hinge there, right about two inches forget the right angle from my camera. The knuckles themselves are also right at two inches in length. So you can see the pin diameter inside there is gonna be 3/8 of an inch or about 9 1/2 millimeters. And 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 US. So if you are looking for a four inch wide by six foot long continuous hinge for your trailer, this is going to be a great option for you.

That's going to complete our work for today. Again, I'm Michael with etrailer.com. Thanks for watching..

  • Availability Of 3" Wide 4' Long Aluminum Hinge With A 3/8" Pin
