Product
Meet the Terrawagen Bug Barrier Window Vent (No-See-Um 20×20 Mesh), a finer-mesh version of our original Bug Barrier designed for customers who want added protection from smaller insects while still getting clean airflow.
Each vent features a built-in 20×20 fine mesh screen over every opening to help keep out no-see-ums and other tiny bugs that can sneak through standard screens. The vent body is made from durable, paintable ABS plastic for all-weather use and a secure fit.
Installation is simple. Roll down your window, twist, and slip the vent into place, then roll up the window.
Sold in pairs. Each set includes one driver side and one passenger side vent for balanced airflow.
