Product Description Crack a window for airflow without turning your van into an open invitation for bugs. The Terrawagen Bug Barrier Window Vent drops into your front window channel and gives you a clean, secure way to vent the cabin while keeping insects out. Each vent is built from durable ABS plastic and includes a built-in screen on every opening, so you get real cross-flow air without the “camping with the windows down” consequences. It’s designed to fit snug and drive-ready, helping reduce wind noise compared to improvised solutions. Installation is quick: roll the window down, slide the vent into place, then roll the window back up to lock it in. Sold as a pair with one driver side and one passenger side vent for balanced airflow.
