The Werner MT-22IAA is a multi-position ladder with a 22 ft reach height and a 375 lb duty rating. It has 32 adjustable positions and works as five ladders in one: an extension ladder, a double-sided twin step ladder, a stairway ladder, a 90 degree wall ladder, and two self-supported scaffolding bases. The scaffolding positions do not require additional scaffolding brackets.
The ladder uses Werner's POWERLITE rail system, which makes it lighter than previous Werner 375 lb multi-position ladders. It has shatterproof aluminum J-locks and oversized, impact-resistant push knobs. The telescoping design adjusts to different jobs, and it can be used for both 1-person and 2-person work.
It has an extra wide flared bottom for firm support and slip-resistant feet. The size refers to the ANSI definition of length (ANSI A14.2-2017 6.2.4).
