The halfrack underframe is made to transform your Half Rack into a complete tourney ready storage system. It is designed to perfectly accomodate the UAF Toolbox, and Halfrack Underframe Drawer but can also hold clear plastic bead or hobby storage cases popular for token/dice storage. It can also easily hold your custom or high end dice trays.
Best of all, the Halfrack Underframe is independent of your halfrack and fully compatible with any TCS Halfrack. So you can use your storage solutions for whatever game system you are using that day.
