The Mastercraft 17’ Telescopic Aluminum Multi-Task Ladder, Grade 1, is an option for a wide variety of applications that require some additional height to get finished. Thanks to an innovative multi-position design, the aluminum ladder can quickly reconfigure between 4 different positions. Depending on the task at hand, the ladder can serve as a twin stepladder, a stair ladder, an extension ladder, or a pair of multi-height scaffold bases. This folding ladder has a CSA Grade 1 rating, which means that it can hold a working load of up to 250lb (113 kg). Regardless of the task or the project at hand, this Mastercraft ladder offers heavy-duty support with its powerful aluminum frame, wide base, and safety thanks to its positive locking mechanism. To make the ladder easier to store for those with limited utility space, the ladder can also fold into a compact form when not in use.
