The patented TacTie Polymer Joining Clip (PJC) is a heavy duty injection molded hardware component developed by the Maxpedition design team, and it comes in 2 sizes: PJC3 and PJC5. It is used to integrate accessory pockets and pouches onto packs, vests, ATLAS surfaces, PALS surfaces and MOLLE equipment in an interlocking manner. The TacTie PJC is secure when properly woven but may be disengaged by hand without the aid of tools. They are backwards compatible with older Maxpedition pouches backed with webbing as well as fully MOLLE / PALS compatible.
