Product Overview
Togen’s SL46H is a hurricane-grade wind louver engineered with high-strength one-piece molded blades. Featuring an inverted U-shape profile with drainage holes and three-point fixation, SL46H prevents blade shaking under high wind pressure and rapidly channels rainwater away. It has passed the AMCA 500 wind-driven rain test.
