"The 6' L Silver Spring Folding Aluminum Wheelchair Access Ramp with Handrails increases accessibility to entryways, patios or similar locations where steps pose a problem for individuals with limited mobility. With a compact design, it ships folded to save you money and unfolds easily upon arrival for easy installation in your space. The included 4' platform adds space to pause or turn at the top of the ramp if you have a storm door or need to make a tight turn due to the layout of your space. Manufactured of lightweight, high-strength aluminum with a slip-resistant surface texture, this ramp is weatherproof and durable for years of maintenance-free use. The two-level handrails accommodate adults and children who walk by themselves or assisted, in addition to individuals in manual or electric wheelchairs or scooters. Pre-drilled holes allow for permanent installation, or place the ramp and platform without where temporary access is needed. If the ramp is being used in a space that is required to meet ADA guidelines, it must be used with rises no higher than 12""."
