Extension for Ceramic Cartridge is a precision solid-brass stem extender that lengthens the reach of faucet or shower handles when wall thickness or trim depth changes. Finished to match your set in chrome, brass, nickel, bronze, copper or gold.
When wall finishes change, handle reach can too. Our Extension for Ceramic Cartridge solves it elegantly, adding the extra length your handle needs to sit perfectly on the escutcheon without wobble or over-tightening. Machined from solid brass for long life and a precise, play-free fit, it’s the clean, invisible fix behind classic Bellistri metalwork.
Designed for selected Bellistri faucets and shower valves that use our ceramic cartridges (Onyx, Waterspring, Dronning, Venice, Florence, and others). For a perfect fit, match your faucet’s model code or send us a photo of the existing valve stem.
