To test the weight of your ramp door, you will want to get the door all the way down to the ground and then on a scale of some kind (a bathroom scale can be used for this if it's the only thing available). This will be when the door is at its heaviest point. As long as this weight is 230 pounds or less, the TRC Conventional Ramp Door Spring for 8' Wide Enclosed Trailer # 362SA8HD will be a great option and will definitely make lifting the ramp significantly easier.

With that being said, 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.
