The Caster Plate feature is an additional floor component with wheels to aid in the mobility of a WhisperRoom™. The Caster Plate also provides a substantial amount of downward noise control.
It adds additional mass in the downward direction and provides a 4′ air buffer below the WhisperRoom. This feature is highly recommended for applications where low-end, structurally transmitted noise is a problem.
Note: This option adds five (5) inches to the overall height of a unit and may be purchased at any time. For ease of assembly, however, it is recommended that the Caster Plate is purchased during the initial order.
