Shelt^r is a canvas tent which can be easily mounted on any type of underground without ropes and stakes. It has the shape of a simple, square house like children would be drawing. A very basic but iconic design indeed. The frame is made of bent steel plates that are galvanized after having been assembled and welded. The steel tubes that unite both frames are also galvanized. The frame is covered by weatherproof fabric that comes in a wide variety of colors. This fabric has a guarantee of 10 years. The fabric is firmly stretched over the frame and fastened with 3 straps with ratchets under the tubes which support the floor. These straps are then hidden under the wooden floor that supports the tent.
