When bringing a duct into the chamber our Bell-mouth or Chamber Entry Connectors offer a further level of quality finish.

Bell-mouths accept ducts from 89mm to 110mm in outside diameter and provide a smooth duct end whilst stopping the duct from pushing into the chamber and restricting access.

Entry Connectors accept HDPE ducts in 32mm, 40mm, 50mm and 63mm diameter. They are a compression fit to both the chamber wall and the outside of the duct. Duct hole plugs cap off any drilled holes ready for simple future and duct access.
