This is about the Coopers of Stortford Door Canopy They have misrepresented the dimensions. I purchased four of these for the area between our kitchen and garage doors. Coopers state that each additional extension adds 1.23 metres. 4 = 4.92 Metres, so I drilled the holes, fitted the four units and the total length is actually 4.75m not 4.92 as claimed. 17 cm short! 6.6 inches. This means that the kitchen door is not covered. I tackled Coopers and they really weren't interested and suggested that I returned them.What good is that when they have already been installed. Ant reputable company would offer a remedy. I suggested that they could send me the materials to extend one by the missing dimension. Not interested. What is more important is that they would not admit the mistake and refused to change the claim in their brochure. So what about other customers who will have been duped? Incompetent and arrogant. Trading standards must be informed.
