#12 final keybushing caul for key pin size .129″
This is a single shouldered FINAL caul for installing the second bushing (and felt sizing) on pianos with key pin size .129″
For the front rail we suggest using the DS-129, as it has double shoulders.
Please review the “About Keybushings” and “Keybushing FAQ” page if you do not understand the two caul system.
