As its name implies, the Roll-A-Ramp Portable Access Ramp is designed to roll up like a sleeping bag. Thus, when not in use, it can be stored in a variety of locations-e.g., closet, porch, vehicle bed/trunk. It consists of series of 12-inch-deep, slotted panels (available in six different widths) that attach to one another via special connecting links. Each panel, with built-in safety rails and made of aluminum, weighs approximately 4-6 pounds yet will reportedly support 1,000 pounds. To accommodate an intended use, the Roll-A-Ramp can be lengthened or shortened by adding or removing panels.
