This custom made ladder is suitable for industrial use or as a backup ladder for a building or house. Thanks to polyester straps and aluminum ladders, this ladder is flexible and lightweight. This model has rubber spacers that prevent crushing hands against the wall and put feet on the rungs without risk of slipping. Approved by the European Union, this evacuation ladder is easily rollable (foldable) and transportable. La Corderie (Brussels) has patented this product for rescue or evacuation.
