The 105XBRM Series has three different configurations for mounting that include the 105BX junction box, the 105BM mounting bracket, and the 105PM pipe mount attachment. The unit can be mounted on ¾" NPT using the 105PM pipe attachment. It can also be surface mounted using the 105BX junction box, or wall mounted using the 105BX junction box with the 105BM mounting bracket. All three mounting options are non-conductive plastic fixtures and do not provide earth-ground continuity when attached to metallic wiring systems. They are intended for use with the 105XBRM visual signals only when earth-grounding is not required. They can only be used with metallic wiring systems when installed at the end of the run.
