Simple and easy-to-use. Push the Tongue into the entry hole and the Tongue will slide past any insulation or obstructions in the wall due to its unique smooth, flat shape. Once the Tongue has exposed itself at the exit hole, you will now need to tape your cables onto the rear of the Tongue. You can now pull your cables through making sure that you guide the cables through smoothly eliminating any damaged cables.
