Extension Ring 

The Caroflow “Easitrim” Extension Rings have 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. 
 
Due to their unique designs, the “Easitrim” will allow for drainage from any level and, if necessary, can be reduced by trimming with a hacksaw on-site or before delivery. 
 
Each “Easitrim” Extension Ring is supplied with long, threaded stainless steel fixing studs. 
 
Extension Ring a) as above, will suit all 50mm and 75mm Circular Outlets. Extension Ring b) as above will suit all 100mm and 150mm Circular Outlets.
