This kit supplies durable vent protection for common RV heater and furnace openings, combining a rectangular screen for water heaters and two circular screens for furnaces, plus spring hooks and a simple installation tool. Built from high-grade stainless steel and rubber trim, the screens keep airflow clear while resisting rust and staying easy to maintain. The package is compact and includes extra fasteners to secure the screens in place and reuse them when needed.
The kit includes one rectangular screen sized 8.5" x 6" x 1.3" that fits most suburban water heater vents and many RV water heater models. Two circular screens (2.8" diameter x 1.3" depth) are sized for common Duo-Therm and Suburban furnace exhausts. Always compare the screen dimensions to your vent openings before ordering to ensure a proper fit.
Installation is straightforward using the supplied spring fasteners and the included installation tool, designed for one-person use. The springs clip into vent slots to hold the mesh firmly; the tool helps compress and position the springs safely without scratching or bending the screen. Removal is equally quick for seasonal cleaning or maintenance.
Screens are made from high-grade stainless steel mesh with a rubber perimeter that resists corrosion and maintains shape. The stainless construction wipes clean with a damp cloth or mild detergent and air dries quickly, so routine upkeep is minimal. The rubber edge reduces metal-to-metal contact and helps prevent scratching of vent frames.
Designed for vent protection, the mesh pattern preserves necessary airflow for combustion and exhaust while blocking insects, nests and larger debris. These screens are sized to sit over external vent openings without obstructing critical clearances; however, confirm compatibility with your unit’s manufacturer guidelines to ensure safe ventilation. Use as a protective accessory, not a replacement for manufacturer-recommended components.
Who is this for: RV owners, seasonal travelers, and fleet operators who want a low-maintenance, reusable solution to keep water heater and furnace vents clear of insects and debris. This kit suits those with Suburban and Duo-Therm style furnaces or common RV water heaters who prefer stainless durability, quick installation, and replaceable fasteners for long-term protection.
Q: Will these screens stop rodents and wasps from entering vents?
A: The stainless mesh blocks insects, wasps, and most small debris; it reduces rodent entry but may not stop determined pests—combine with proper RV pest control for best results.
Q: Can I install the screens myself without professional help?
A: Yes. The kit includes spring fasteners and an installation tool for one-person installation and easy future removal.
