Evacuation Equipment FAQs

Are fire escape ladders adjustable to fit different window sill depths?

Yes, some fire escape ladders are adjustable such as the Rollo roll-out ladder. However, the most important measurement is the wall thickness unless you have extremely deep windowsills.

If your wall or sill depth is especially large (more than 20 inches) ladders such as the Easyscape fire escape ladder that are independent of the wall or sill thickness may be the most suitable.
