Since the angles of each bracket manufacturer are different, the height and depth are uncertain. But the width can usually be estimated based on the sector.
The distance between 58mm tubes is currently 76mm in the industry, so the center width of 26 tubes is (26-1)*76=1900. Additionally, the outermost vacuum tube is usually 70mm from the edge. , and the width of the bracket is 1900+(70*2)=2040 mm. The water tank must be wider, estimated at 1900+(170*2)=2240 mm.
To summarize: According to the 58mm vacuum tube, the stand is approximately 2040mm wide and the water tank is approximately 2240mm.
