Dundas Jafine PSC4WX is a 4-inch ProShield exhaust cap designed for residential venting applications. The cap uses a spring-loaded damper that opens under airflow and closes when inactive to prevent backdrafts and pests, and includes a removable center shield for lint and debris cleaning. The unit features a molded caulk edge for installation, a UV-resistant coating, and is paintable for exterior matching. It is suitable for bathroom fans, dryers, and range hoods.
