TONDA RV Square Furnace Vent Screen

One square vent, one square screen. If the rest of the rig is already defended and a single opening still gapes, this is the exact-size patch — same stainless mesh as the full kits, no spares to shelf.

• Single square screen for one exposed heater vent
• Fine mesh stops insects; heat exhaust flows free
• Marine-grade stainless for year-round exposure
• Includes mounting spring and silicone strip
• The tidy fix when you only need one
