Overview

The Allen-Bradley 855T-BPM25 is a pole mounting base for 70 mm stack light modules in the Control Tower family. Rated for operation between -25 to 70 degrees C with polycarbonate housing and available in black, this mounting base provides a secure, stable platform for stack light installation in industrial control applications. The product was discontinued by Rockwell Automation as of October 01, 2019, making it a valuable surplus or replacement unit for legacy systems still in operation.
