JCJ Mud Dauber Screen for RV Furnace Outside Fitting HVAC Heater Control Valve

The JCJ Mud Dauber Screen (also called an RV furnace vent screen or flying insect screen) fits over the outside fitting of an RV furnace. It keeps mud daubers, wasps, spiders, and other insects from building nests in the vent opening. Nests can restrict airflow and cause furnace performance problems.

Key Features:

• Stainless steel construction resists corrosion and holds up outdoors
• Screens out mud daubers, wasps, spiders, and other pests
• Designed to let air flow to and from the furnace
• Installs with tension springs and an installation tool
• Made for RV furnace and fan unit outside fittings

This JCJ screen gives RV owners a simple way to protect the furnace vent from nesting insects and debris. It is available in several part numbers within the same product line.
