Compact collapsible ladder - GIF

[Frank S]

Had a roofing contractor use one (like it) to go up on my roof, about 5 years ago now. He was a skinny young man, but I've never been able to get Frank S' concerns out of my mind. (That, and I'm already ladder poor.)

If I think about it I will try and remember to drag mine out and show you the locking system. Poorly designed in my book but drilling out the locks and installing lynch pins would solve all ot that only thing would be the hassle of using lynch pins
My truck driver friend bought it thinking it would be handy to carry on his rig due to the compactness the problem is he weighs over 280lbs and that is above the rating
