Video Transcript for Polar Hardware Enclosed Trailer Parts - Doors - H300 Review

Today, we're going to be taking a look at the 3" wide continuous steel hinge. It's going to measure 6' long. This is also called a piano hinge. These type of hinges are used for a variety of applications. You'll find them on tool boxes, different types of flaps, and they are commonly used for trailer ramp doors. Now, this one in particular is made from a mild steel construction. It is strong and durable, and it will resist rust and corrosion.

It's not going to do as great of a job as stainless steel, but it's still going to do a good job. It's still a nice design, mild steel. The unit's going to rotate 270 degrees, so it's going to allow for full opening. I do want you to notice that there's no predrilled holes on the unit. What that does is it makes it easier for welding applications, and it makes it easier to kind of customize it for your application.

That way, you can drill out the holes where you need them to best fit your particular application. Right now, the hinge is completely flat. If we take a measurement of that in this position, edge-to-edge, that's going to measure 3" wide. The internal pin size . There going to be a that runs right through all these knuckles here. That pin's going to give us a diameter of 1/4".

The gauge of steel that the hinge uses for its construction is 0.074". Then the over all length of the unit, measuring from edge to edge, is right on 72" which again is going to measure 6' long. Now this can be cut to fit your need. You can cut it anywhere along. I do recommend cutting right between where the knuckles separate. The knuckle links, that's each one of these pieces right here.

The knuckle links on the unit's going to be 1" long. That's going to do it for today's look at the 3" wide continuous steel hinge that measures 6' long.

This piano style stap hinge is exactly what I needed. I can drill holes to attach or not drill and weld with my mig to attach. Very heavy duty, and well made, can be cut down if need be. Great for fabrication use and price is hard to beat, got here quickly undamaged. 105059

Excellent product and dealings. I might suggest a little more attention to packing. It arrived okay but when I lifted the box up the hinge fell out of the bottom. Guess lucky it didn't fall out in shipment. More reinforcement of the taped areas would help. 356407
