Brandguard's named soffit and undereave vents are listed for wildfire-area use with specific sizes and sheet-steel construction with galvanized screens.
The OSFM listing identifies UE3011 at 22 by 3.5 inches, UE3021 at 14 by 3.5 inches, UE3031 at 14 by 5 inches, and UE3041 at 22 by 3 inches. It also covers UE3051 at 22 by 5.5 inches and UE3061 at 14 by 3 inches. The longer CS3011 and CS3021 models measure 120 by 3 inches and 120 by 5.5 inches, respectively. Each size belongs to its named model.
The units use 26-gauge hot-dipped galvanized sheet steel with a phosphatized coating and a galvanized screen with 1/8-inch square mesh. OSFM cites ASTM E2886 as the test protocol. That citation belongs to the assembled vent, including the specified construction; the mesh dimension alone is not the tested product.
For a soffit or undereave opening, match the model code and dimensions before comparing the steel and screen specification. Follow Brandguard's installation instructions and product data sheets, and confirm the exact listing in GOVmotus. The shared listing collects several vent sizes without making their model numbers interchangeable.
