 Fire dampers pairing
The patented WK25 rectangular re dampers can be paired side-by-
side or vertically (not more than two) using the custom connection
kit (see section Accessories and spare parts) which includes an intu-
mescent gasket to be placed between the two dampers.
The pair of dampers, may be installed in vertical wall in the same way
as a single damper.
