I have 4 roof access ladders with grab bars and anti climb devices. These are for mainly commercial applications but could be used in barns or on houses for an escape route (if you take off the anti climb device). These cost about $1200-$1500 dollars new. They are aluminum in construction, have the mounting brackets and all but one has the side trim. They are, from ground to top step; 11'3", 12'3", 13', 13'9". They can be joined together to make a longer ladder as long as a splice bracket is used and you have ample mounting area for the brackets. They weight about 100# each. I would take $150 each for them, you pick them up in LR near Joe T Robinson school.
