Please note that some codes mandate handrail spacing, and or vertical slats. ADA requires handrails on any ramp with a rise of 6 or more, and PVI recommends handrails on all but the shortest ramps unless other provisions are made for the safety and assistance of the user. Using the ADA-recommended slope of 1:12 is preferred however, when space is limited these system will accommodate slopes up to 2:12. Anchoring may consist of lag screws or bolts into wooden surfaces, or anchor bolts drilled into existing concrete, and/or pre-cast pads or poured in place. Secure anchoring for the first pair of posts at the bottom is especially important because this adds necessary strength to the lower end of the handrails. Each freestanding ramp must be anchored at the upper and lower end. Platforms must have a minimum of one leg anchored on each of the two opposite sides. Ramps can be disassembled, moved, and reassembled at a new site in a new configuration and length. Each leg is independently adjustable to compensate for settling of the supporting surface using a half-inch wrench. These ramps don't have to be permanently attached to a building. 30 mins for landings site prep, transport, and anchoring not included.
