This spacer is placed between your existing tray and the OEM ledge. It adds an extra 10mm in depth - deep enough for any phone with any cases. Access to the original USB ports is preserved or use them with any Qi pads. This item is for those who like to maintain the original Piano Black look or for those who would prefer to wrap that piece yourself.
Note that they will not fit with the full size sunglasses trays but will pair well with the 3/4 tray.
