The Lee Precision 90195 Double Disk Kit is a nylon reloading accessory that upgrades the Lee Auto-Disk and Lee Pro Auto Disk powder measures by raising the powder hopper so two metering disks can be stacked at one time. This drop-in modification effectively doubles the powder capacity of the measure while still permitting extremely fine charge adjustments in .1 grain increments, giving handloaders more flexibility between charge weights without swapping disks between reloading sessions.
The kit ships with 2 metering disks and the mounting screws needed for installation, and is built from durable black nylon. It installs on a current Lee Auto-Disk or Pro Auto-Disk powder measure with no permanent modifications, making it a low-cost upgrade for reloaders who already own one of these Lee powder measures and want greater on-board capacity and finer adjustment control without replacing the measure itself. The Double Disk configuration is intended for metering smokeless powder charges for handgun and rifle cartridges.
