Hammer weight for Roland keyboard, for black keys only. A broken key hammer is usually the cause of a key that suddenly feels clunky, or won't return to is normal 'rest' position.

This part has been discontinued by Roland, and Syntaur has now manufactured an improved version of this hammer (in foreground of photo). These hammers are also available in octave sets or in full 88-note sets.

Check out this blog post for helpful instructions on replacing these hammers.
