Atwood 2004-model RV furnaces vent through an outside fan/vent fitting that mud daubers, wasps, mice, frogs, and spiders will happily nest in if it's left open. This JCJ screen mounts over that fitting to keep them out.
It's made of stainless steel mesh with tension springs, sized so it won't restrict the airflow the furnace needs to burn and vent properly, and it installs with the included tension springs and installation tool.
A low-cost way to protect an Atwood 2004 furnace's outside vent from nesting pests.
