Professional double-sided aluminum ladder for painting. The ladder is light and easy to transport. The wide and strong side rails are connected by straps that prevent the ladder from spreading too much. The steps are welded to the side rails, which guarantees stability even if the ladder is on an uneven surface. The product has a set of conveniences, such as the extended third step with anti-slip ridges and grooves and the bucket hook mounted on the upper part of the ladder. The ladder is narrow and does not take up much space when folded.
