Jeff: Hello everybody. This is Jeff at etrailer.com. Today, we're going to take a look at this conventional dual-spring ramp door spring for up to an eight foot wide enclosed trailer. Has 120 pound inaudible 00:00:12 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 the risk of injury, it'll help take on the weight of the trailer door so that you don't have to.
Now this one is a dual-spring design. The dual-springs will eliminate the risk of the ramp door collapsing and causing damage or injury. Basically, if one of the cable fails, the other spring will prevent the trailer door from free-falling. This spring will also reduce wear and help prevent damage to your door hinges. And this spring is designed to be mounted one way for proper operation.When you go to install this, you want to make sure the cable drums, these are the cable drums right here, these will need to be mounted.
They're marked this one over here will have an R on it for right-hand side. And then they spray paint it black also to indicate that. This one here will be stamped L for left-hand side. And they spray paint it red to indicate that. But basically when you go to mount this, the right side right here, this is what will mount onto the curbside of the trailer.
The left side is designed to mount on the road side of the trailer.Now this spring system can be modified to fit your specific application. Right now, I have the springs all the way out to the end for the largest. But you can slide the spring and the cable drum down and then cut the shaft to a shorter length to fit your application. The range on this, with it all the way out like this from this end to that end, is going to be 95 and five eighths inches wide. And then if we slide this all the way to the shortest or the narrowest trailer door...
I'll just loosen our cable drum there and we'll slide that with the bearing. So if we go all the way, from here to here, the minimum would be 54 and three quarter inches. And again, if you need that, then you could just cut off this shaft to a shorter length. So again, the application will be 54 and three quarter inches all the way to 95 and five eights inches wide trailer door.Now, it does include everything here on the table. It includes your mounting brackets with the hardware. It includes 150 inches of one eighth inch diameter cable and the hardware for the cable and the set screw covers. Now this is a nice sturdy steel construction. It is made in the USA. Again, the specs on this, if we put this all the way out, if we measure from this end to that end, it's going to be 95 and five eighths inches long, the diameter, the widest diameter will be the drum itself, is four and three quarter inches. Spring capacity is 120 pounds.And I do want to mention a warning when you do try to install a spring, it is recommended that only individuals who have experience winding these torsion springs should install this product because when you start winding this, it gets a lot of tension. It is dangerous. So if you've not worked with a torsion spring system before, we do recommend contacting a local garage door company to help you install this system. But that should do it for the review on this conventional dual-spring ramp door spring for up to an eight foot wide enclosed trailer. And it has 120 pound spring capacity.

Fits 54-3/4" to 95" wide trailer doors.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.
Works very well,I was worried because I had to cut down the length ,had to take off one spring because of how short I had to make it.But I am very pleased and the door lifts great.
Installed like I new what I was doing why didn’t I put this on years ago? It works great
This was a great purchase. I modified the rear door on my trailer and this came with everything that I needed to install it. We use the trailer almost every weekend for 3 seasons. it works just as good now as the day I installed it.
This system has worked flawless for a year would recommend it to anyone needing one
Best service ever

Review from a similar M3 Ramp Springs in Trailer Ramp Springs
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".

Jenny N - 02/19/2022Review 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.

Review from a similar M3 Ramp Springs in Trailer Ramp Springs
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
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
