Enter/exit vehicles. Create entry ramps to homes, schools, or offices. Then, roll it up and put it away! Versatile ramp design uses 2 bolts to connect each section, allowing you to add or subtract length as needed. What’s more, each section can be “frozen” to the next to create a bi-fold or a permanently attached fold-up ramp. Plus, cambered sections provide a smoother on/off at the top of the ramp. Lightweight, extruded aluminum construction with black anodized surface and built-in safety rails. 10-YEAR WARRANTY.
