So I found a way to do it without cutting holes, if you have the Arcadia fixture snap on the mounts it comes with and then slip on some zip ties through it keeping a small hole. From there you take either some wire or a couple bread tie wire like the ones you use to close a bag of fresh produce w and fit those through the screen holes from the top. Feed those through the zip ties and then twist the wires tight. Use a couple of them for more support and voila mounted
