I'm modifying my curbside charging station so I can permanently mount an HPWC or UMC behind a lockable hinged door in the bollard so I don't have to attach and reattach everything when I charge. The Tesla plug and cable will be stored behind the lockable door, and when I need to charge I'll just unlock the door, pull enough cable out, and plug it into the car. But I'll need an extra UMC to do this. Can't find anywhere on the Tesla site where they're available yet but I to get everything set up I'll need to obtain one before delivery. Any ideas or does someone have a spare they are willing to sell?
