Union Mini Disk Black

The Union Mini Disk Black is a replacement mounting disk kit for compatible Union bindings. Its small footprint leaves more of the snowboard free to bend beneath your feet, giving a flexible, surf-oriented connection. Choose it to replace a damaged or missing disk on the right baseplate, or to prepare a compatible binding for another board. It keeps the original Mini Disk approach rather than changing the binding's mounting system.

The compact contact area matters because a binding influences how the board flexes underfoot. Reducing that footprint lets you feel more of the board's own movement when steering, pressing and rolling between edges. This is a construction choice, not a promise that every snowboard will feel soft. Your board, binding chassis and stance still work together. The disk must fit the recess in the baseplate correctly before any mounting hardware is tightened.

The kit contains two Mini Disks and mounting hardware, enough disks for both bindings. These work with 2x4 inserts and The Channel. A board's insert pattern and a binding's disk interface are separate checks: matching one does not automatically confirm the other. Lay the hardware out before fitting, then set your stance width and angles deliberately rather than copying the position of a loose screw.

Union lists Strata, Legacy, Contact Pro, Milan and earlier Ultra and Falcor models within the Mini Disk family. Ultra and Falcor from 2022 onward are excluded from this particular kit. Model names can carry across different generations, so use the binding's year and existing disk as your reference. One Size describes this replacement kit; it does not mean that it fits every Union baseplate or every snowboard mounting pattern.

During installation, keep the disk seated flat and start screws by hand so the threads engage cleanly. Follow the binding and board instructions for tightening and verify that the binding cannot rotate after assembly. Union says not to use Loctite or chemical cleaners on these disks. Remove dirt gently, let the components dry and inspect around the slots when servicing your setup. If the old disk is cracked or the mounting recess is damaged, have the complete connection checked.
