Is the expansion user-selectable? Can I switch between "regular" and "wide" or is it just going to come with a wider post? I'm not sure if I need the extra width, but I'd like to have the option if I can switch.
AldreneanIt comes with a minimum width of 2keys wide on each end. If you purchases the expansion kit it acts as a spacer which then allows you to increase the number of keys you are able to for between the outside plates. I have two of these already from here and they are awesome!
