It's all a matter of length.
To choose the correct fire escape ladder you first need to work out which windows you plan to use as your exit points and then, for each window, it is simply a matter of deciding how many stories it is off the ground.
You need to take into account sloping ground. A front first floor window might be as high as a second story window at the back of your house. So make sure you factor in the actual height from the window to the ground.
Our QuickEscape ® Emergency Escape Ladders come in 12 ft and 20 ft lengths.
When in doubt, buy a longer emergency fire escape ladder!
