This mounting bracket and retaining clip fits the original style rechargeable AMB TranX 160 and TranX 260 Transponders. This bracket is not used with direct-powered units.
The old style TranX Transponders can be identified by the flat front, the hook at the bottom of the transponder, and the loop at the top of the transponder. These units were manufactured until 2005.
The current version has a rounded front, a recess in the bottom, and a hole through the top. This style uses the TranX 160 / 260 Mounting Bracket for New-Style Transponders, Part No. 5016.
