We are currently running a promotional campaign offering a gift of <trial grip tubes (1m) of each size> and <printing samples> for customers who are introducing the drum-type grip tube for the first time for cable marking and tube markers (Letter Twin) consumables. The grip tube securely grips wires with three folds, making it difficult to slip off and allowing for movement. It is suitable for wire marking of plug-in terminal blocks (ferrule terminals). If you would like to see what it is like or try it before purchasing, please feel free to contact us through the "Grip Tube Sample Application Form" in the related links. *Applications are limited to one per person. *Samples are scheduled to be shipped within 10 days after the form is received.
