Why does my sleeve length change on combination fire smoke dampers in CAPS on certain line items on my selected pricing worksheet or submittal? I want the sleeve size I entered. (This occurs when an OCI is selected).

The sleeve length only extends when you have a height of less than 279.4 millimeters (11 inches) with an OCI option. Because the actuator has to be mounted horizontally due to the height constraint, the sleeve length must be extended. When this occurs, the OCI option must be mounted in the sleeve in front of the actuator. The sleeve must be extended to provide enough room.
