The Regulating Rack with Template Set provides the profile of a grand piano's strings along the strike line. Select sizes from The Template Set to match the sections of a grand action and fix them to the rail so their lower edges represent strike (see the Keystep Protocol). Spanning the entire action, the Regulating Rack either hugs the sides of the keyframe on a workbench or rides in tracks on a Custom Keybed (in a RS Deluxe). LED lights in the rail illuminate both templates and hammers.

Letoff racks provide letoff for a section. Regulating Racks provide the entire strike profile and change its height as needed for the whole action.
Applying The System
The Setup and Order of Operations guides you step by step and the Laminated Protocols let you tick off steps as you go, so you don't get out of order or leave something out.
The Regulating Rack's rail has LEDs that illuminate both templates and action. The Hammer Hanging Jig has its own LEDa, too. And Lighting Rails come in four sizes to shine light wherever you need it.
