Builders Best 111391A PWM622 4 Inches Wide Mouth Plastic Vent Hood with Bird Guard Flush Faceplate White

Product Description

The BUILDERS BEST 111391A is a 4 inches wide mouth plastic vent hood designed for wall venting applications in residential and light commercial buildings. Built under the PWM622 product family, this vent hood is manufactured from polypropylene molded plastic and features a flush faceplate in white, making it a clean, low-profile solution for exterior wall penetrations. It ships fully assembled with an 11 inches riveted tailpipe, so installation is straightforward and does not require additional fabrication on the job site. The hood includes an aluminum trim plate that sits flat against the wall surface for a finished appearance. A back-draft flapper is integrated into the design to prevent outside air, wind, and pests from entering the duct system when the fan or ventilation equipment is not running. The bird guard pest grid uses a 1 half inches by 1 half inches mesh opening that snaps in and out for easy removal and cleaning. This feature helps block birds, rodents, and insects from nesting inside the duct run. The hood accepts a 4 inches pipe diameter and is suited for bathroom exhaust fans, kitchen range hoods, dryer exhaust alternatives, and general HVAC ventilation systems. HVAC technicians, contractors, and builders working on new construction or retrofit projects will find this hood easy to handle and install. It is manufactured in the USA and carries no Prop 65 designation. Note that this hood is not the recommended primary choice for dryer venting. If used for that application, the pest grid screen should be inspected and cleaned frequently to prevent lint accumulation, which can create a fire hazard. The vent type is wall, and the product is sold individually as a single unit.
