The main feature of the 2273-202 is its fully transparent casing, which allows the installer to visually confirm that the conductor has been fully inserted and properly stripped. It has a special test port at the back for measurements with a multimeter or tester, while the white color coding helps with immediate identification of the 2-position model. Its robust construction makes it resistant to vibrations and ideal for junction boxes with a high concentration of cables, where organization and speed are essential elements.
