Key Punchings

View Key Punching and gather the shims and related tools piano technicians rely on to set key height, achieve a consistent keyboard level, and fine‑tune dip and aftertouch on both uprights and grands. You’ll find front rail and balance rail punchings in paper/cardboard for precise incremental adjustments and in felt for durable base cushioning and noise control, offered in multiple thicknesses (often color‑coded) and convenient package sizes or mixed assortments for shop stocking. Keyboard punching sets provide a full range of gauges for bench work, while dedicated front rail and balance rail options let you replenish the sizes you use most. Complementary tools such as key punching lifters enable quick installation and removal around the rail pins without disturbing adjacent keys, and straight edges support accurate leveling checks across sections of the keyboard. Whether replacing worn washers or dialing in a new regulation, these components are sized for standard rail pins and help maintain uniform key height, smooth travel, and quiet operation throughout the action.
