StackTech Roll Holder is an innovative upgrade for your workspace organization. Thanks to its two-piece design and a telescoping bar, this Roll Holder can be easily mounted on both the front/back and sides of StackTech tool boxes. The bar's 18 mm diameter accommodates rolls with smaller cores, making it perfect for a wide variety of wire spools and tapes. At the same time, the Roll Holder accepts rolls up to 6.5 inches in outer diameter, so it can be used as a convenient paper towel holder. The versatility of the Roll Holder goes even further, as it can be swiftly repositioned within your stack with the simple push of two quick-release buttons. And to swap out rolls, two yellow bar removal buttons will come in handy. This adaptability ensures that you can optimize your StackTech system setup to meet your needs and workspace configuration. Increase your efficiency and productivity by adding the StackTech Roll Holder to your StackTech tool box setup
