Consumer Reports also judged six 12-and-a-half-foot telescoping extension ladders "Not Acceptable": Telesteps 1205 Types IA, I, and II (discontinued but may still be available), 1600 Types IA and I; and Xtend & Climb 770. Consumer Reports did not report on other telescoping ladders by Telesteps or Xtend & Climb, but a stepladder by Telesteps was very highly rated. Separately, CR notes that safety standards for consumer ladders are not mandatory. Instead, there are voluntary standards published by the American National Standards Institute (ANSI) that outline types based on a maximum weight. http://www.kcbd.com/story/5251323/consu ... oavailable
