This lot contains two No-Pest Vent 4-inch J-Block or wide-mount dual door wall vents in tan, model NPJT. Constructed from high-impact, UV-resistant polypropylene plastic, these vents are designed for use with dryers, bathroom exhaust fans, and range hoods. They feature a unique dual-door magnetic design that provides a tight seal to maximize airflow, reduce energy costs, and eliminate backdrafts while keeping birds, insects, and rodents out of your home. The units lack lint-trapping screens or louvers to minimize fire hazards and meet structural building codes. These items are in used-fair condition, showing signs of prior use or minor cosmetic wear, and come from a mixed lot inventory. Components like duct tubes or mounting screws may need to be sourced separately depending on your installation requirements
