This question is regarding Sirrus Thermostatic Cartridge (no Thermostat) Standard - SK1500-2

SK1500-2 - External Barrel Outside Diameter

Hi, further to your response on the above subject, I have measured my old cartridge to be 28mm diameter and the new cartridge to be 28.5mm. The casing diameter which sleeves over the external cartridge barrel is 28.5mm (see attached photos), so therefore the new cartridge does not fit with my existing cover plate.



Thanks in advance
