Runner holder for organizing and managing scale model and miniature runners (sprues, gates). The modular design ensures that you can expand or adjust the channels quickly to accommodate the different widths and lengths of runners. A strip of dry erase white board sticker can be added to the nameplate to serve as a writable labeling surface. Multiple bases can be connected together to hold whole model kits with a large number of runners. All parts are friction fit and easily disassembled.
