I can find plenty of Delta crystal lavatory knobs with diamond shaped mounting holes but none with the hex mount. I need three of these handles. Mine are all stamped with MP 14 inside near the hex shaped stem hole. I can't cross reference this part number anywhere on the internet including Delta.com. This handle I've found on your website looks to be the right one except for the mounting issue. I blew up the schematic and the stem for this one is diamond shaped so it won't work. I need hex shaped stem mount. Please help me find the right part number.
Thank you for your question. Some knobs have a hexagon shaped insert. If you see a hex shaped mounting hole and stem, the handle insert is probably stuck on the stem of the ball assembly. Please try soaking it use a half and half white vinegar and water solution, and pull the gray hexagon shaped piece off. You should then be able to install this handle.
