This kit upgrades your Vario to the metal portaholder.
The kit includes the Black Plastic Rear, the Metal Belt casing, and the Metal PortaHolder.
This kit is NOT compatible to the Vario W (986 model) and would disable the capability of grinding by weight. New 886 models or Vario units purchased end of 2014 and into 2015 to current day, come standard with the Metal PortaHolder Accessory.
Very good quality, upgrade was easy, you need only a screwdriver!
Real improvement...worth the money
