Ladder Central supplies a huge range of Multi-Positions Ladders
The Multi-Position telescopic ladders can be used in many unique configurations as an A-frame, extension, staircase and 90-degree ladder. The ladder can be separated into two small trestles to form a trestle and plank scaffolding system.
Some models have the built-in levellers to allow you to always find level ground by simply extending it down to the desired height. The ladders that come with these levellers are Little Giant Leveler and Epic models.
