Flexible sided ladders are not suitable for emergency escapes. It is extremely difficult to use these ladders safely if you are in any way incapacitated.

Wide enough for a single foot, these specialist ladders are lightweight, and make virtually no noise when deployed. They are an alternative to wire sided or wooden rope ladders. Constructed from textile sides and carbon fibre rungs they are ideally suited to wet environments.

Ladders can be suspended from a wide variety of anchor points. One important point to note is that, to reduce wear and excessive loading, the wire sides must not be distorted beyond an angle of 20ยบ from vertical.
