This ladder will perform all of the same tasks as the standard tripod ladder, but due to all 3 legs being adjustable, it opens up all kinds of further opportunities, making it the most popular type of ladder in the range. The rear 3rd leg is telescopic and adjustable in 150mm stages. The two front legs can be independently adjusted in 50mm steps with spring loaded locking pins.This allows the ladder to be used on steps and stairs and at virtually any angle on quite steep slopes whilst still providing a stable, safe, comfortable work position.
