Our Kiefer's "Slot File Boxes" are America's best selling auction ticket box. We designed these decades ago and produce them 100% in our own shop. We notch our own dividers out of plastic to insure these will last for years. They are ruggedly built out of wood to take some banging around in the field. Our aluminum clerk sheets holders and other forms holders are top quality. Whatever you need for clerking or auction accounting we've got it.
