Products / RS-400 Raft-A-Vent

A 22.5 in. long bird-block intake vent strip, one inch thick, designed to fit between rafters on top of the blocking in open-rafter eave construction, printing 18.75 square inches of net free ventilating area (NFVA) per piece. It is available in white or black, power-nailable or screw-down, and is meant to run continuously in every rafter bay as the intake half of a balanced ridge-and-soffit ventilation system. Cor-A-Vent's product literature does not print a warranty term for its soffit vent line.
