EV Charge Cable Under Door Cover

I designed this fitting so as to pass the charge cable for my EV under the garage door (the charger is in the garage, the car parked on the drive).

Cutting a channel in the garage floor and passing the cable through this fitting provides a permanent solution that does not interfere with the operation of the door.

Unfortunately, I didn't record any measurements for the cutout in the floor, so you'll have to work it out for yourself. The fixing holes allow screws and plugs to be used to secure it. I also filled around the edges with a light grey silicone sealant.

For reference, my charge point is an Ohme Type 2 wall charger. The cable channel in this fitting is 20mm diameter.
