I can't imagine my size 13 EEE's climbing on those thin rungs. Kile TM51 I have a managery of ladders some aluminum telescope folding some extension some simple step ladders some non conductive even a tubular telescoping one that is only 30" tall when collapsed and over 12 feet tall when fully extended all have a rating of 300+ lbs 1 even folds to become a scaffold.
But I don't see that thing joining my selection
