Hard plastic castings of an actual Motorola APX 6000 Series Radio (with standard 3.5inch tall Impres/Impres 2 battery). These plastic castings are made to give fire service leather workers the ability to accurately size and adjust tensions on radio buckets & radio retention systems when access to an actual APX radio is not available. These provide an accurate height, width, and general radio shape. The plastic has been sanded smooth with a minor polish. The remote mic attachment is excluded. Note that users with extended or longer life batteries will have different sizing needs.
