Lomanco Omni Ridge Vent (4 ft)

Lomanco® Omni Series Ridge Vents are available in two styles and many variations. The roll version comes in easy-to-handle 20-foot and 30-foot lengths, while the stick version comes in 4-foot lengths. The regular Omni style is traditionally installed using a hammer, while the Lo-Omni style, with its low profile, can be installed using a nail gun.

💡 Key Features of the OR Series Ridge Vents:

🌀 Engineered with External Venturi Baffle
Designed to optimize airflow by creating suction that pulls hot, moist air from your attic—even in low wind conditions. Keeps your attic cooler and your roof structure healthier.

💧 Moisture-Blocking Underlap Joint
Each unit includes a weather-sealed underlapping joint that helps block rain and wind-driven moisture from seeping beneath the shingles.

🚿 Drainage Built-In
With four drainage openings per foot on both sides, these vents actively channel away water, reducing the risk of buildup and ensuring maximum efficiency.

🏠 Tailored for 3/12 Roof Pitch
Pre-molded to fit 3/12 slope roofs precisely—no cutting or bending required, saving installation time while maintaining a seamless fit.

🛡️ Integrated Water Shield (Model OR4-S)

🔩 Complete Hardware Kit Included (Model OR4-N)
Each OR4-N model comes ready to install, including 30 durable nails per vent—no extra hardware needed.
