Fitted Insulators

High-grade Wooden Insulator with Prevention of derailing Function

Fitted Insulators (for use with GP): G-Fs/G-Fw/G-Ff

High-grade wooden insulators
that reverberate rich sound tone from below your feet.

Fitted Insulator receptors are capable of snuggly and deeply receiving the casters due to their 2-step cavities that match the arc of the casters. This structure enables the product to stabilize the piano. After mounting, in addition to stability, they are also capable of preventing the piano from becoming unseated or jumping, which are likely when the piano vibrates up-and down.

Chosen for these reasons

Sound tone

Due to being made of wood, sound tone expands as it is conveyed directly into the floor from the piano.

Caster stability

The fitted board receptors are able to deeply receive casters due to their 2-step cavity and shape that corresponds with the arc of the casters. This structure enables the product to stabilize the piano.

Function of the securing kit

Using a fixture developed by us, it is possible to secure casters with strongly tightened bands.
This mechanism prevents casters from becoming unseated from the insulator due to up-and-down vibrations.

Does not directly damage the piano

There is no need for fastening screws or nailing, it does not directly damage the piano, floor or wall.

The ascent of piano by the caster is minimal.

Restricts the height so that piano pedals can be comfortably pushed. (Approx. 11mm)

Compatible with a wide selection of models
