These Flip-Up Dock Ladders have a quick-release safety pin that locks the ladder in the down position and keeps it stored up and out of the way, so it stays clean when not in use. 21" wide. 21" high handles. Extend 12" onto dock. 750-lb. capacity. Wide-step ladders have a 4" wide rounded step for more stability and comfort. 12" between each rung. Mounting hardware not included.
