A rebar clip is provided for joining a larger diameter rebar to a smaller diameter rebar transverse to the larger diameter rebar. In a first embodiment the clip includes diameter reducing tabs extending into upper arches of the clip for engagement with smaller diameter bars crossed on top of larger diameter bars. In a second embodiment the clip includes diameter reducing tabs extending into lower arches of the clip so that the clip may hold larger diameter bars on top of smaller diameter bars. A guide track for a clip applying gun is provided which allows for use with either version of clips and with clips of the same nominal diameter for joining equal size bars.

1. An apparatus for applying a clip to first and second reinforcing bars, comprising: a barrel having a distal end and a clip receiving cavity;a hammer received in the barrel;a main drive, connected to the hammer, for reciprocating the hammer within the barrel:a trigger assembly, connected to the main drive, to actuate reciprocation of the hammer; anda clip track connected to the barrel, the clip track aligned with the cavity for guiding a string of frangibly connected clips into the cavity, the clip track having a longitudinal axis extending transversely from the barrel, the clip track having a cross-sectional shape perpendicular to its longitudinal axis, the cross-sectional shape having a base portion having a base width defined between two base sides, and the base portion having a base height, and a neck portion extending from the base portion above the base height, the neck portion having a neck width defined between two neck sides, the neck width being less than one half the base width, and the neck portion having a neck height above the base of less than the base height. 2. The apparatus of claim 1, wherein: the base sides are substantially parallel to each other. 3. The apparatus of claim 1, wherein: the neck sides are substantially parallel to each other. 4. The apparatus of claim 1, wherein: the neck portion extends for the entire longitudinal length of the track. 5. The apparatus of claim 1, wherein: the neck height is greater than one half of the base width. 6. The apparatus of claim 1, further comprising: a clip string retainer connected to the neck portion of the clip track, the retainer being movable relative to the clip track between a retracted position and an extended position, the retainer extending beyond the neck portion when in the extended position; anda spring biasing the retainer toward the extended position. 7. The apparatus of claim 1, further comprising: a handle extending laterally from the barrel; anda brace attached to the handle and to a distal end of the clip track, to support the distal end of the clip track. 8. The apparatus of claim 1, wherein: the clip receiving cavity is sized to receive a clip having a nominal size corresponding to a standard clip for joining two crossed rebars of the same given nominal diameter; andthe neck portion of the clip track permits the apparatus to receive on the clip track a modified clip for joining a smaller diameter rebar crossed on top of a larger rebar of the given nominal diameter. 9. An apparatus for applying a clip to first and second reinforcing bars, comprising: a barrel having a clip receiving cavity sized to receive a clip for joining two equal diameter crossed rebars of a first diameter; anda clip track connected to the barrel and aligned with the cavity for guiding a string of clips into the cavity, the clip track having a base portion having a base thickness and a base height, and the clip track having a neck portion extending from the base portion and having a neck thickness and a neck height, the neck thickness being less than one half the base thickness, and the neck height being less than the base height, so that the clip track can selectively receive and guide into the cavity either a string of clips for joining two equal diameter crossed rebars or a string of clips for joining a smaller diameter rebar to a rebar of the first diameter. 10. The apparatus of claim 9, wherein: the neck has two substantially parallel neck sides, the neck thickness being defined between the neck sides. 11. The apparatus of claim 10, wherein: the base has two substantially parallel base sides, the base thickness being defined between the base sides. 12. The apparatus of claim 9, wherein: the neck height is being greater than one-half the base thickness. 13. The apparatus of claim 9, further comprising: a string of frangibly connected clips received on the clip track, each of the clips having upper and lower arches sized to receive two equal diameter crossed rebars of the first diameter. 14. The apparatus of claim 9, further comprising: a string of frangibly connected clips received on the clip track, each of the clips having a lower arch sized to receive a bar of the first diameter, and each of the clips having an upper arch including a pair of diameter reducing tabs defining a slot therebetween;wherein the neck of the clip track is received in the slots of the clips. 15. An apparatus for applying a clip to first and second reinforcing bars, comprising: a barrel having a clip receiving cavity sized to receive a clip for joining two equal diameter crossed rebars of a first diameter;a clip track connected to the barrel and aligned with the cavity for guiding a string of clips into the cavity, the clip track having a base portion having a base thickness, and the clip track having a neck portion extending from the base portion and having a neck thickness less than the base thickness, so that the clip track can selectively receive and guide into the cavity either a string of clips for joining two equal diameter crossed rebars or a string of clips for joining a smaller diameter rebar to a rebar of the first diameter; anda string of frangibly connected clips received on the clip track, each of the clips having upper and lower arches sized to receive two equal diameter crossed rebars of the first diameter. 16. An apparatus for applying a clip to first and second reinforcing bars, comprising: a barrel having a clip receiving cavity sized to receive a clip for joining two equal diameter crossed rebars of a first diameter;a clip track connected to the barrel and aligned with the cavity for guiding a string of clips into the cavity, the clip track having a base portion having a base thickness, and the clip track having a neck portion extending from the base portion and having a neck thickness less than the base thickness, so that the clip track can selectively receive and guide into the cavity either a string of clips for joining two equal diameter crossed rebars or a string of clips for joining a smaller diameter rebar to a rebar of the first diameter; anda string of frangibly connected clips received on the clip track, each of the clips having a lower arch sized to receive a bar of the first diameter, and each of the clips having an upper arch including a pair of diameter reducing tabs defining a slot therebetween;wherein the neck of the clip track is received in the slots of the clips.
