  "textContent": "submitted by loopy to diy\n9 points | 4 comments\n\n\nI am adding a UV light to my furnace coils. I decided to cut an access panel for easier cleaning and access to the UV light. I did not realize there were these triangular end covers for the A-frame of the furnace evaporator coils.\n\nI don’t see them anywhere online when looking up diagrams of furnace coils. When I search online, it is also not clear if these covers are necessary. Are these covers beneficial? Or can I take one side off to fit the UV light underneath the A-frame?",
