Expert Verdict Reviewed by the SuperArbor Pro Desk

Strip intake vents like the S400 are a quick retrofit over solid soffit or where manufactured soffit panels do not provide enough intake area. Lay strips so the required intake NFA per foot is met and keep them clear of insulation blocking; add baffles where insulation could choke the intake path. Black is the most common color choice to hide the strip against dark soffits.

Use ladder and fall protection safe practices when working at eaves and soffits.
