Before I go into a plumbers merchant(s) and ask, with the possibility of been laughed out of the shop! Is it possible to buy replacement radiator wheelheads and lockshield covers for radiator valves, (not TRV). I have looked at Screwfix, BES and Toolstation but they don't appear to stock them. I have only ever seen two different shapes to the spindle tops, either square or an oblong shape with rounded ends, mine are the oblong shape, so will any cover with this shape fit? I obviously cannot take my valves with me to the shop to try them! I realise I could buy the valves and use the covers but as I need 10 of each, I would be left with 10 new valves with no heads or covers.
Cheers
John
