This ladder is quite incredible. Most ladders that you've seen are either A-Frame (triangle with bracket in the middle) or extension (the ones you lean against a roof). This ladder, however, offers a simple yet ingenious innovation, as it dispenses with brackets in favor of a hinge. This makes for a versatile ladder that can be used as an extension ladder, an A-frame, at a 90-degree angle, or even as scaffolding.
With ever-shrinking available space in homes and garages, you can combine three or more ladders into just one. Little Giant claims this is the last ladder you will ever own and they may just be right.
