I am selling this item due to moving, as I no longer need it. I purchased it for high-place work such as cleaning the windows in the atrium and outdoor tasks. Due to scheduling constraints, this listing is only available today. It has been used only two or three times. It is made of aluminum but is very sturdy. It can handle up to 150kg. No instruction manual included. It will be shipped in the original box. If you can use it, please consider purchasing it. Thank you.
