Roll-A-Ramp® is unique because it can be built to any length. Roll-A-Ramp® is flexible in that it can be built to ADA specifications 12:1 (1′ of ramp per 1″ of rise). However, this length is typically not needed in most locations nor is it feasible in most home locations. Ramp length will depend on your situation and your individual need. Because it is a portable ramp, it is not required to comply with ADA guidelines
