Baffle Blade (K-Blade)

Built-in protection from rainfall. Baffle blades are designed with a blade catch at the center of the blade, for capturing rain as it enters the louver. Drainable models quickly drain water and prevent water infiltration through the louver.

Baffle blades are available for stationary louvers, severe weather louvers, and combination adjustable louvers.
