We bought the door canopy and extension kit after reading " It was easy to fit " written by " Mr P.B.. What utter rubbish, the canopy is a nightmare to put up. we thought it came as seen in the catalogue ready to put up, but NO IT DOES"NT.. You have to struggle and bend a flat sheet of perspex and put rubber seals on before slotting the ends on, this is not a job you can do single handed.. the whole design is wrong relating to the holes in the framework, difficult to put a pilot hole in top wall anchor hole and to make matters worse if you have attempted to erect the canopy and you want to change your mind and return it you will struggle to get assistance in doing this, I did. i have now given up and will not be buying anything else from Coopers
