Continuous Ridge Vent

Gravity Ridge Ventilators

Gravity ridge vents are a low cost method of ventilating large open floor plans that don’t require air conditioning. Typically used in conjunction with louvered air intake systems, these vents provide weather resistant ridge openings that may be regulated with a damper. Continuous installation allows operation in banks of multiple sections, and may be motorized with actuators.
