MC4 Cable Entry

Picked up some rubber grommets that I tested with the piece of metal that was cutout for the fan.

After knowing the fit was accurate, I masked the area on the roof and drilled the holes.

The gland was leveled with several layers of butyl tape to compensate for the roofs ridges and secured with 3M Heavy Duty 3M Mounting Waterproof VHB Foam Tape and Lap Sealant.
