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 galvanized steel drainable blade louvers are available in 4" and 6" depths.
A variety of accessories and finish options can be chosen, to meet all of your ventilating needs.
