Review on 🔥 Fire Escape Ladder: 5&6 Story Portable Emergency Solution, 50ft Length, Anti-Slip Rungs by Scott Rose

My 13.5 year old baseball and football player was wondering how to carry it in the big box it ended up in at the top. One reviewer said don't unroll it so I don't know how to grab the handles to see how it fits because it's too heavy to hold on windowsills and try on. Also, we are on 3.5 floors, so I have to pull out the screen to try, which is not easy from 3.5 floors. The window sills in my house are wide, so look at your window sills, it's not as easy as it sounds to check. Is it big, maybe 18x18x18 out of the box? It doesn't come in a bag or its own packaging, it's just a bunch of metal steps strung together.
