If larger dimensions of dampers are required (for bigger airflows), the devices are provided by 
the Manufacturer as multi-assembly sets (damper sets). Assembly sets are made of a suitable 
number of single dampers of the basic type as well as flat bars and connecting elements. 

 
 
Basic dimensions of mcr PL1 dampers have been presented on the drawing below.
