BRILLIANT SERVICE. The Sales office was very helpful to me in working out how to go around the corner of the wall using two standard rails of different lengths and a hinged elbow so as to achieve an appropriate angle there. They then organised for one end of each rail to be left open for the elbow whilst the other ends were filled with the end stops I had selected; fully fitted and firmly glued in place. Absolutely BRILLIANT and more than I had expected. The product arrived promptly with massively long screws to fix to the wall; even I was happy! The only thing that might(?) have improved matters would have been some sort of thin plastic bases to help bed the brackets against the uneven surfaces of the brick walls.
