Variant CU2-L500
Variant CU2-L500
CU2 damper with a tunnel casing extension at the wall side to facilitate the connection to the duct when the supporting construction
is thicker than 100 mm. This version also ensures that the damper blade doesn't exceed the casing at the wall side (up to a height of
500 mm), which allows to connect a grill or a bend directly on the damper flange or to use a circular connection.
