The Xtend+Climb® pro Series 785P is a heavy-duty telescoping ladder used by thousands of commercial contractors and serious do-it-yourselfers. As Xtend+Climb's tallest telescoping ladder, it opens by the ft to 15-1/2 ft and retracts down to 36-1/2 in, making it great for the highest and hardest tasks on the job. Many customers favor the 785P because it stands at a towering 15-1/2 ft with a 19-1/2 ft average reach height. So when new heights need to be reached, the 785P is the ideal alternative to the traditional extension ladder - only this adjustable ladder is lightweight enough to be carried with one hand and small enough to be stored in the front or back of a truck. It easier to transport to and from a jobsite while saving space in storage.
