• the guide bar is designed to be relatively high, so that the guide bar is at the same time designed as a twist protection.
• Conventional insulation displacement terminal strips have two opposing rows, wherein the guide bar is higher than the distance between the rows. This ensures that the tool does not accidentally cut through the connected wire, but only the protruding part of the wire, which can then fall between the rows.
