Products / Lomanco 750 Slant-Back Vent

The Original 750 is Lomanco's slant-back static roof louver (box/turtle vent), with an overall size of 16 x 20-5/16 x 5 in., an 8 in. opening, and 50 sq in of net free area. As part of Lomanco's 700 Series roof louvers, it is made of embossed aluminum finishes (with 750-G/750-GS galvanized steel and 750 copper offered as specialty variants), features an upward-discharging louver design intended to prevent roof discoloration and bird/animal intrusion, and is offered in mill finish, brown, white, black, weathered bronze, and forest green (aluminum only). The product-listing table marks the base 750 model with Miami-Dade County, Texas Department of Insurance (TDI), and CSA approval checkmarks; the 750-S variant (metal screen insert) adds a WUI (Wildland Urban Interface) prescriptive-compliance checkmark.
