Expert Verdict — Reviewed by the SuperArbor Pro Desk
Match the vent to your gable's pitch and opening before ordering, since triangle vents are pitch-specific and hard to resize. Balance gable exhaust with adequate soffit intake so air moves through the attic rather than short-circuiting between two gable vents. The Mill finish suits natural metal looks, while White blends with painted trim. Follow net free area guidelines when calculating how many vents the attic needs.
Installing a gable vent requires cutting into wall framing; verify the opening location avoids electrical wiring and structural members, and follow fall protection when working on a ladder.
Choose your Lomanco 900 Series aluminum triangle gable vent in the size and finish that fits your gable.
