Thank you for your question on the central vacuum system hoses. Any of the current carrying hoses, except for the CH610, CH615 and CH620, will work with the 330N wall inlet and the CT600 power head. The hose currently in our line that will work with both of these units is the CH515. Please contact the Technical Service Department at 888-336-6151 if you need further assistance.
