Extension Rings

The Caroflow “Easitrim” Extension Ring has been designed for use where a single level drainage “upside-down” warm roof system is specified.  This will raise the grating by up to 110mm to allow for the height required from the waterproof membrane to the finished roof surface.  They can also be stacked should further height be required.  Available for all circular roof outlets, as well as the Balcony Outlet and Gulley Outlet (Spigot).
