Ideal Standard 22mm Concealed Valve Extension Kit — A961107NU
The Ideal Standard A961107NU is a genuine factory-engineered 22mm extension kit designed for Ideal Standard and Trevi built-in (concealed) thermostatic shower and bath/shower mixer valves. When a rough-in valve body is chased too deeply into the wall cavity, or when retrofitted wall tiling and boarding add extra depth, the standard cartridge spindles and threaded collars cannot reach the external control handles and faceplate. This complete 22mm kit bridges that installation gap, extending the internal operational splines, fixing sleeves, and escutcheon threads forward to enable correct fitting and secure handle engagement without altering pipework or wall structures.
