A 45 Degree Tee or 135 Degree Tee is used to create a gentle gradual bend in a flue run. It can be used to change a chimney run from a horizontal to a vertical when used with a 45 degree bend. This component minimises the resistance to flow because of the angle created with the vertical axis. The lower section of the 45 Degree Tee comes with a bottom cap that can act as a cleaning and inspection area to allow for easy access to the vertical flue and requires an inspection cap to close. The 45 Degree Tee is attached to the external wall by the Base Wall Support. WE DELIVER TO ALL PARTS OF THE UK AND REPUBLIC OF IRELAND.
