Works great.
We used this for lifting a folding attic ladder as we needed something pretty strong. Our client still raves about it to this day!

Wasn’t used for its intension, but worksd perfectly! Easy setup and installation. Spring tensioner was easy to set and reduced ramp door closure weight substantially. Would purchase again.

Do you have a question about this Trailer Ramp Spring?

Availability of Ramp Spring that Fits 30-36 inch Wide Opening
That specific part number isn't available but we have the same spec ramp spring with the part # 362SA8207 which is 94 inches wide, a dual ramp setup, and has a 150 lb capacity. For a smaller size that fits a 30-36 inch wide door instead you'd want the part # 362SA4 which fits door widths that are between 24 and 44 inches.

Can TRC Enclosed Trailer Ramp Spring Be Cut Down
An Enclosed Trailer Ramp Spring, like part # 362SA4, can be cut down to fit 23-3/4" to 43-3/8" doors. Ramp Spring # 362SA5 can fit 31-5/8" to 55-1/2" inch doors. They are customizable to fit the space available in your trailer as well as the door size so for your door I recommend # 362SA5. These springs are unique in that they are not the high torsion springs that require professional assistance for installation. They are self adjusting.

Why Doesn't Conventional Ramp Door Spring 362SA4 Come with Instructions
That's a really good question and I do apologize for confusion on that. But the reason instructions aren't included with the Conventional ramp door spring part # 362SA4 is because they aren't intended for the DIYer to install. It is recommended that only individuals who have experience winding torsion springs install this product. If you have not worked with a torsion spring system before, we recommend contacting a local garage door company to install this system. These can be dangerous...

Does 4 ft Ramp Door Spring Come as a Dual Spring Option
The dual springs are for larger ramp door applications. Since you have a smaller 4' door you just need a ramp with a single spring like the Conventional Ramp Door Spring # 362SA4 you were looking at.
view full answer...
Length Of The Ramp Door Spring # 362SA4
The Conventional Ramp Door Spring # 362SA4 is in fact 44 inches. The spring assembly is able to be cut down to 23-3/4 inches minimum. The spring helps reduce wear and helps prevent damage to the door hinges. The system can be modified to fit your specific application, just slide the bracket and cable drum down and cut the shaft to a shorter length. The spring has a sturdy steel construction. It will fits doors from 24 inches to 44 inches. I attached a review video link below.

How Much Does Conventional Ramp Door Spring Weigh
The Conventional Ramp Door Spring # 362SA4 weighs 12 lbs.

Door Spring Recommendation for 50-75 lb Cellar Door
The 120-lb Capacity Self-Winding Ramp Door Spring 362SW61 isn't available anymore but we have this one instead that I believe will work better for you: - Conventional Ramp Door Spring # 362SA4 This is designed for 24" to 44" wide doors and has a spring capacity of 70 lbs so for your 50-75 lb door this should make it a breeze to open!

Ramp Spring Recommendation for a 33 inch Trailer Door Ramp
Since you have such a skinny door I would recommend you get a spring assist like the Ramp Spring # 362SA4. This assembly can be cut down to 23-3/4 inches minimum so it will be a great fit for your custom ramp.
