The best selling clamp in the piano industry fills
a much needed requirement for a foolproof,
attractive upright and grand piano locking device.
The clamp is made from a special hardened steel and
has rubber sleeve to protect the piano's finish.
Clamp has a maximum opening of 6-1/8" wide, which
should fit most any type of piano fallboard.
A wooden shim is provided for use when installing on
pianos with smaller fallboard widths.
This device consists of a lock and two keys,
which are keyed alike. Screws are provided to attach
the clamp underneath the keybed.
