What is the typical width of continuous opening covers?

The typical width of continuous opening covers is between about 2 and 4 inches wide. This dimension is standard for ensuring adequate ventilation while providing a barrier against pests and potential weather infiltration. Covers in this range also facilitate the necessary airflow in various applications, such as in eaves, soffits, or attics, helping maintain appropriate indoor air quality and thermal regulation. Proper sizing is crucial to support ventilation systems effectively and to comply with building codes or best practice guidelines, which prioritize both functionality and safety.
