The extended Apple Lightning cable is thicker than the cable that came with the iPhone and iPad or the Twelve South Lightning cable. It should not be forced into the channel in the base as this may damage the cable. The better solution, if you need a longer Lightening cable for your HiRise, would be to use your original Apple Lightening cable or the Twelve South Lightning cable that came with a HiRise 2 Deluxe, and add a usb extension cable.
