Thanks so much. I just ordered mine based on your setup and the price. I will give this a try, hoping I can make the same slots. I think if I have the mounting bracket in hand I can visualize better how to measure and slide the opening over the mounting bracket, thanks again!
I like the slits cut here, can I ask what tool you used to cut them and how you measures them so precisely?
I assume you used an oscillating tool? But the measurements which each would be different I kmow, but did you hold it up or how? TIA
