This is the same bracket and clip as supplied with the current style Rechargeable AMB TranX 160 and TranX 260 Transponders. The clip is now retained with a built-in lanyard for added convenience. This bracket is not used with direct-power transponders.
The newer style TranX Transponders can be identified by the slightly rounded front, the black section at the bottom of the transponder, and flat top (no protruding loop). These units became available beginning in 2005.
The older (pre-2005) version has a flat front, a hook on the bottom, and a loop at the top. This style uses the TranX 160 / 260 Mounting Bracket for Old-Style Transponders, Part No. 5012.
