Allen-Bradley 855E-BSB Stack Light Mounting Base

The Allen-Bradley 855E-BSB Stack Light Mounting Base is the surface-mount base for the 50 mm 855E Control Tower stack lights, providing a rugged panel interface that lets the signaling tower sit flush against a control panel while still allowing straightforward wiring and maintenance access. As part of the 855E family, this base supports 50 mm stack light modules and is designed for secure, clean installation on a flat panel surface, facilitating precise alignment and cable routing in manufacturing cells, machines, and process lines. In the 855E lineup, the surface-mount base variants include PG16 conduit mounting and, for other configurations, 1/2 in NPT threaded surfaces, reflecting compatibility with common enclosure and conduit practices. With a black housing aligned to the 855E system, this base enables a compact, high-visibility signaling stack for machine status, alarms, and process indication in industrial settings. Designed to work with Allen-Bradley 855E 50 mm light modules, this base supports quick panel mounting and dependable signaling in busy production environments, from packaging lines to manufacturing cells and machine rooms.
