The drainable blade louver is designed to minimize water penetration through the louver. This is
accomplished by positioning a gutter at the outer edge of the louver blades. The gutters help to reduce the cascading of water
from blade to blade. Drain spouts are located at the jambs to collect the water from the louver blades and channel it away to
the louver sill.
Carnes extruded aluminum drainable blade louvers are available in 2", 4" and 6" depths. Stationary or adjustable blade
models can be chosen, to meet all of your ventilating needs.
Carnes Model FPBB 4" drainable blade louver has one of the top performances in today's louver industry.
