Helpful Expert Reply:

The spring capacity for the ramp door spring will need to meet or exceed the weight of the door. If you have a 195 lb door then the closest option we have that will be able to lift this is the Conventional Ramp Door Spring for 8' Wide Enclosed Trailer part # 362SA8HD which has a 230 lb weight capacity. It fits doors between 94-3/8" to 95-3/8" wide.
