MAGIC UNION solid rubber threshold ramps are a safe and easy way to transition a raised surface with a power scooter, wheelchair, walker, or by foot around the home and office. Each threshold ramp features beveled edges for a smooth and gradual approach to and from a raised surface. The one-piece design is portable, handy, and creates a finished look at the base of a doorway. Molded channels in the ramp surface allow water to drain away and provides excellent traction in any weather. Make doorway access easy with a Silver Spring rubber threshold ramp! Made with durable 100% recycled rubber for years of reliable use.
