Homeowner needs a reliable soffit-to-ridge ventilation system to prevent ice dams but cannot install standard baffles due to inaccessible top plate area in the attic.

Standard pink foam baffles cannot be installed because the top plate area is inaccessible from the attic; box vents alone are insufficient to prevent ice dams.

Adjustable length (up to 5ft) to bridge soffit to attic
Integrated insulation dams to prevent bypass
Compatible with ridge vents and standard soffit openings

Target Users: Homeowners and roofing contractors in cold climates (Zones 5-7) dealing with ice dam problems on low-pitch hip roofs with inaccessible attics.
