Review on RV Flying Insect Screen: Protect Your RV Furnaces and Water Heater from Insects with Stainless Steel Mesh and Installation Tool by Justin Heynoski

In general the product worked well. I had to modify the springs for the heating element and heating element H2O (round and rectangular shade). The springs were too long and didn't hold the screens in place. Not difficult to do. For long, narrow screens, you will need 4" (very narrow) cable ties for attachment. 5" will go through the screen. With the right zip ties, installation is not difficult, although time consuming. I noticed that some vendors include cable ties. In general I recommend. Only 4 stars due to necessary improvements.
