Model 1614TL Thinline louver combines excellent performance with pleasing aesthetics, utilizing stationary flat blades designed with smooth lines that enhance any structure’s exterior styling. Standard concealed architectural mullions allow for a desirable continuous blade appearance. This thinline louver delivers outstanding performance where a 2" (51), 4" (102) or 6" (152) louver is not practical. Suitable for use in ventilation, exhaust and low to medium velocity intake applications, ideal for use in thin wall and curtain wall applications or A/C units where a full depth louver cannot be used. Available in 1 1/4" (32) deep flanged frame that installs easily in most common wall and mechanical configurations.
