#8 final keybushing caul for key pin size .137″


This is a single shouldered FINAL caul for installing the second bushing (and felt sizing) on pianos with key pin size .137″

For the front rail we suggest using the DS-137, as it has double shoulders.

Please review the “About Keybushings” and “Keybushing FAQ” page if you do not understand the two caul system.
