This is an Emergency Escape Ladder that is permanently mounted under one of the 2nd or 3rd floor windows. It is a very well made unit, worth every bit for such a great addition to your home.
***Why these are better***
These units are far superior to the cheaper, chain, hook type that store under the bed or in a closet.
Will those types be where they are supposed to be when you absolutely need it?
The Pearl unit will be in the same place, every day.
The nice thing about it is that you can create an annual training opportunity for you and your children to actually set it out of the window and crawl down it so they can be familiar with it in an emergency.
Most people do not think a fire, or intruder event will impact them in the future, but if it does how will you get out of the house?
For $250, have that peace of mind to know you have a great option and better chances to save your life.
I had a large old farm house. I purchased 3 of these units, one for each bedroom. After installing (1) I realized that is all we needed. I have (2) units available.
