This 16-foot aluminum extension ladder offers a beneficial addition to any home. You will be amazed by our new system, a strong rung lock. The easy-to-use quick latch locking mechanism offers added safety and security by preventing the rung lock from disengaging the rung. You will be comfortable using this extension ladder on your house. It features a proGrip, and a tread integrated end cap that helps stabilize the ladder and protect landing surfaces. It's resistant to slipping and will limit potential damage to the landing surface. This ladder can extend up to 9-feet. It allows you to reach heights of 15-feet, which assumes a 5'8" person. It features a modified I-beam for a more stable connection, which also restricts twisting. The safety shoes on this 16' step ladder can be swivelled. Use them in tread-down or spike positions depending on the terrain. The heavy-duty foot also features ice picks for stability in ice or winter conditions. This unit meets or exceeds ANSI-rated type 2 safety standards.
