Jeff: Hello everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this conventional single spring, single drum ramp door spring for up to a six foot wide, enclosed trailer, has an 80 pound spring capacity. Now this part will replace your old trailer door spring with this nice heavy duty conventional ramp door spring. This ramp door spring will let you easily lift and lower the door on your enclosed trailer without risk of injury. It is designed to help take on the weight of the trailer door so that you don't have to.

This one here happens to be a single spring and a single drum system. A single spring is on the torsion rod has this cable drum here with the lift cable at the one end to lift the door. It only uses one cable to lift the door in this application. And this system is normally used in snowmobile trailers to help reduce the potential for catching a ski in the cable.This spring does reduce the wear helps prevent damage to the door hinges. Now, when you do install this, the spring is designed to be mounted one way for proper operation.

And the way you can tell that is if you look at the cable drum, it'll be stamped with an R, which means for the right side. And they do also spray painted black here for visual indication of knowing that that's for the right side. The right side is designed to mount on the curb side of the trailer.Now this part will include everything laid out here on the table. The spring itself, the mounting brackets, the hardware for the mounting brackets, the bearing, gives you 150 inches of one eighth inch diameter cable and hardware to install that. And then the set screw cover.

Now this spring system can be modified to fit your specific application.You can slide the bearing and the mounting bracket where needed, and then just cut the shaft to a shorter length. So if we put the bearing on, let's say, you're going to go all the way, to narrow as possible. And if you put the mounting bracket on. So you can see what that all installed, it will fit any words from if we measure this portion 34 and three quarter inch wide trailer door, all the way up to the widest, which would be sixty six and seven eighths inches wide. Now this is a nice sturdy steel construction.

It is made in the USA. Few specs, again. The overall length from this end, all the way to this end is going to be right at sixty six and seven-eighths inches long. The drum diameter, which is the widest diameter on this is about four and three quarter inches diameter.
