Review on 🔒 ABN RV Vent Cover & Install Tool: Protect Your Furnace, Water Heater & Battery from Bugs - 4.5 x 4.5 x 1.3in Camper Trailer Insect Screen by Demetrius Patsion

Installation takes a bit of effort and it's a bit of a hassle to hook the springs securely into the hole you're covering. Tip: Attach one end of the spring to the mesh cover and hook it with the tool, but string the other end from the top back with the tool, tighten the spring and then hook it. This is easier than running the tool through the mesh and trying to push the spring into part of the hole to catch it. You will see when you get it. Make sure you order the right size by measuring carefully. Better a little wider than narrower. Once installed the product works great keeping wasps and other creatures from settling in your heater or hot water flue.
