Allen-Bradley 855T-BPM25 Stack Light Base

Allen-Bradley 855T-BPM25 is a mounting base for the 855T Control Tower Stack Lights, engineered for pole-mount installations and commonly paired with a 25 cm aluminum pole in stack-light configurations. This aluminum base is designed to support industrial signaling towers and is specified for up to 250 VAC operation, with a compact weight of about 0.44 lb (0.20 kg). The part is cataloged as 855T-BPM25 (UPC 662072701249; Unique Product Identifier 855T-BPM25) and is documented as a Rockwell/Allen-Bradley mounting base for 855T stack lights, with production origin in Austria and an estimated lead time of 14 days. The BPM25 variant is referenced in multiple sources as a 25 cm pole-mount option within the 855T family, suitable for control-tower applications in industrial environments. This base was discontinued by Rockwell on October 1, 2019, so current availability has shifted to replacement bases within the 855T lineup; verify compatibility with your specific stack-light head and mounting height when planning an upgrade or retrofit.
