The Standard Upgrade Kit takes advantage of our modular design by utilizing Premium components to allow for screen swapping in the Standard Edition mill. You no longer need to buy an entire Premium Edition to be able to change screen sizes.
The Kit includes 3 screen sizes: Coarse, Fine, and Extra Fine so you can really dial in the consistency based on your preference. NOTE: This does not replace the rotor of your Standard with the Premium Stainless version, only the center section.
Thread the center rod and screw onto the desired screen then place the assembled screen and rod into the aluminum center housing. Thread in the stainless sleeve and tighten securely. You now have a complete center section to use with your Standard Edition.
