Hi George,
Thank you for your question. It would be very difficult to install a runner on a handicap ramp. However, I would recommend our Anti Slip Tape A636, here is the link, http://kofflersales.com/p/anti-slip-abrasive-tape.asp?cid=23
A number of our clients are handicapped and this is what they typically use.
Thank You,
The Koffler Team
