New Baldassin “3-in-1” Underlever System by Renner USA

The New Baldassin “3-in-1” Underlever System by Renner USA maintains the design of the original Renner USA Universal Underlever System, with the flexibility of adding capstans, either in the underlevers or the tray, if desired.

This system allows the damper action to be custom tailored to fit the many different grand piano scales produced over the past 150 years.

The kit includes the underlever tray, the tray ending blocks, pivot pins, a complete set of underlevers (pre-drilled for optional capstans), a complete set of capstans, individually cut action cloth pieces (used with capstan in tray installations), flange screws, the flange keeper wire, tray cushion felt, stop rail cushion felt, damper lever assist springs, and a roll of mylar tape for creating the drilling scale.

The Baldassin “3-in-1” Underlever System can be used to replace:

  • Damper actions that have been damaged or worn out.
  • Damper actions with the underlever top post screw threaded directly into the wood.
  • Damper actions that underlevers with fixed veneer sostenuto pick-up tabs.
  • Damper actions with short-arm underlevers.
