Since 1885, Johnson Controls has developed and refined air control products by providing the highest quality control dampers that fit your application and size requirements. LM-1250 louvers feature:
- Adjustable aluminum drainable blade with a 6 inch (15 cm) deep aluminum frame.
- Adjustable louvers are designed for tight closure. Drainable heads channel water to the side frames, which channel through vertical downspouts and out the bottom of the louver at the sill. These models are efficient at minimizing water penetration.
