• 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.

• 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...

• 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.
