I'm looking at getting the Wall Connector installed in my garage but I'm concerned about how much clearance the actual connector needs as the garage is quite narrow. What I'd ideally like to know is how close can the car be to a wall and still have space to connect/disconnect the wall-connector 'wand'. On a related note, how tight can a garage be before 'summon' gives up? At the narrowest point the opening is around 210cm wide. Any help would be much appreciated!
