Industrial power AHL stepladders that can support a weight of 150 kg. Strong, secure, and convenient to use and transport. These heavy duty stepladders have deep treads and a surface that is strongly ribbed to prevent slipping. For added rigidity, each tread has two rivets. The ladder is more sturdy thanks to front and back stays on the bottom tread and locking side trays that enable positive over center locking while it is in the open position. The front and back legs of the ladders are equipped with non-slip rubber feet.
