JCJ Mud Dauber Screen for RV Furnace | Suburban, Hydroflame, Duo-Therm

A wasp nest in the furnace exhaust is the classic cause of a furnace that lights and then shuts down. JCJ's stainless mesh screens fit over the intake and exhaust tubes of the common RV furnaces, held by the included tension springs, and keep insects out without choking airflow.
