Brief Description: Cut Slot in Sub-Panel for SL40 Comm Tray
The next thing I did was cut the slot in the sub panel for the SL40 comm tray. I drilled 1/4" holes in each corner and then used a dremel cutoff wheel to make the cutout. I then deburred the edges with a file, sandpaper, and scotchbrite pad. The panel can now be installed with all of the trays bolted in place.
