Throttle, Mixture and Pitch contoll cables
 

Good day RV friends.
I dont have my firewall forward kit yet, so therefore the following question. What is the exact diameter of the throttle, mixture and pich controll cable as supplied by Vans. I am doing a trip to the USA next week, and I would like to purchace the firewall passthrough fittings for the said cables from Aircraft Spruce, but I dont know the diameter of the cables yet. I think its in the order of about a 1/4 inch, but I need a bit more specific measurements.
Kind regards
Arie

3/8? diameter.

I just got three if these for the firewall passthrough: https://www.aircraftspruce.com/catal...ickkey=5442479
