  • Main tee connection
    Patent number: 7703258
    Abstract: A main tee with separate clips affixed on its ends for splicing the tee with identical tees in end-to-end butt joints. The tee and clip form a pocket for receiving the projecting end of an opposing clip with a uniform low insertion force. The clip is self-aligning with the pocket and when interconnected the clips precisely align the coupled tees both vertically and horizontally. The clips, formed of relatively strong material, have mutually engageable locking surfaces that ensure a strong joint.
