When retrofitting a CSH-20 or FSV-24/30/35 hull unit on a steel hull, an attachment
flange must be used. Choose the correct flange from the table below, using the length
of the pre-installed tank to determine the raising height.
When retrofitting CSH or FSV-243E/244E hull units, use the OP10-24 attachment kit.
