Step-by-Step Installation
Easily install your Moisture Flow® Soffit Vent in just three steps for reliable and efficient ventilation. With clear preparation, precise cutting, and secure fastening, you’ll enhance airflow, reduce moisture, and protect your home for years to come.
Step 1
Select and Prepare the Location
Choose an area on the soffit where ventilation is needed, ensuring it’s free from wiring or structural obstructions. Measure and mark the vent opening size (4.5” circumference) on the soffit using a pencil or marker.

Step 2
Cut and Align the Opening
Pull the transition flex duct through the opening and attach it to the top of the Moisture Flow® Soffit Vent using a zip tie (not included). For hard ducts, connect the duct to the soffit vent and seal the connection with tape or caulk (not included) for an airtight fit.
