Mud Dauber Water Heater Vent Mud Screen | Protective Insect Screen

Mud daubers and other insects love building nests inside the exterior vent openings on RV water heaters, and a blocked vent can interfere with proper combustion and venting. This screen covers the opening so the pests can't get in and build up there in the first place.

It's a lightweight, low-profile add-on rather than a replacement part, meant to sit over your existing vent as ongoing protection rather than fix a problem that's already occurred.

• Screens the water heater's exterior vent opening against insects
• Helps prevent mud daubers and other nesting insects from blocking the vent
• Lightweight, low-profile design
• Simple add-on installation over the existing vent

Check your water heater vent's opening size before ordering to make sure the screen covers it fully.
