Bonsour Greg,
The older smaller size strike racks will hold 50 of the, older smaller size/type of strike cases. But, it will NOT hold any of the newer bigger size/type strike cases.
However, the newer WHITE racks for the bigger size strike cases. Will hold 50 of the bigger size strike cases. They WILL ALSO HOLD 60 of the older smaller size strike cases. Or, in different amounts in different size combinations. Hope this helps.
Dan
