The PP902T is an interlock system with an easy grip front and an angled paddle that captures and connects two pieces of corrugated cardboard. To install, simply insert the clip from outside of a corrugated box via a simple die-cut, then grasp the front crosspiece to turn and lock into place. As the back paddle turns upright, it compresses and joins the two cardboard while providing support and security to the tight closing. To detach the joined corrugated walls, turn to unlock the box clip and remove it from the die-cut in seconds.
