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. And the spring capacity, as we mentioned, is 80 pounds.But that should do it for the review on this conventional single spring, single drum ramp door spring for up to a six foot wide enclosed trailer, has an 80 pound spring capacity.

Review from a similar M3 Ramp Springs in Trailer Ramp Springs
I have a home repair buisness and repair and install garage doors so it was a great benifit in intalling this ramp door spring. The quality of these are right up there with whats on your garage door just lighter duty springs. Be sure to weigh your door to get the correct springs. Customer service was beyond great, thank you to all reps.

I bought this to retrofit an enclosed trailer that was originally built with exterior springs.
This is a major improvement over the other style and money well spent. Everything went smoothly according to the instructions. I was good at 38.
My door is now a "one hand wonder".

Review from a similar M3 Ramp Springs in Trailer Ramp Springs
Everything worked out great. Installed on a snowmobile trailer. The door originally only had a spring system on the bottom of the door. It took 2 people to close. After installing the M394FR it is a 1 arm operation. Highly recommend this product

First, shipping was really fast. After I ordered I received a email saying my order had already shipped. I ordered on a Tuesday and was able to install my equipment during the weekend. I have a smaller 6 x 10 trailer and I only utilized 1 torsion spring which gave me a back up spring for reserve. After installing the unit with new tension cables my ramp door works smooth and I’m really happy to have my trailer back in service again. etrailer understands the importance of getting customers product out as soon as possible. I thank you for your professionalism and will recommend your company in the future.

Great price and fast shipping. Packaged well and has everything you need besides the wrenches rods to wind spring. Very easy to install. Since I had been brackets already it took me about 45 minutes including taking the old one off. And I already had the rods to wind spring up which is a must. Thanks.

Review from a similar M3 Ramp Springs in Trailer Ramp Springs
Worked well, cut down the bar to fit our trailer needs and bolted right up. Right side pulley was bent, (Probably from Shipping). Working with them for a replacement. Just took the pulley off the old to get the trailer back on the road. Installed quickly with 2 guys and everything was as described when purchased.

Took less than 4 hours to fit and install. I added a ramp to a double door cargo trailer was a strain to close until I added this spring now can close with ease. Perfect for my now motorcycle trailer
Review from a similar M3 Ramp Springs in Trailer Ramp Springs
Recently purchased this trailer ramp dual spring to replace my single spring. The original spring roller from factory snapped. Cut to fit it to 75 inches. Perfect replacement. Instructions very detailed and right on. Install time with spring adjustments 1 hour. Delivery was fast and product was priced competitively. Very happy. And dual springs just make more sense.
