Hi, I want to fit radiator covers on 2 radiators. The radiators are deeper than standard flat radiators, the ones with a grille on the top for the heat to come out upwards iyswim. Anyway, I've bought the covers, the one for the smaller radiator measures 1115 mm so is longer than the 780mm radiator, but that's fine. The potential issue is with the larger radiator. The radiator itself is 1400mm, not including the valves at each side and on the box it says the radiator can measure up to 1415mm with a diagram showing the top of the radiator NOT the valves. The cover measures 1500mm and I'm concerned it's not going to fit...anyone with any advice/experience? Tia
