The manufacturer assures us that when cleaning heavy snow from the roof and the grass, Lilun's dual-use roof snow rake is a competent helper. The snow rake is made of aluminium alloy material and can be divided into four sections. The height can be extended from six feet to eighteen feet. The snowplough is made from nylon fibre and polypropylene. The black colour increases visibility while working on the snowy ground. The rake can be assembled and removed without any hand tools. http://lilun.imb2b.com/
