Mounting *

Bracket mount is the recommended mounting for installing Echo fixtures longer than three feet. The BRK mounting is for individual fixtures and features a bracket at each end for surface mounting and includes a separate cover that fits over a standard 4” octagonal junction box. Additional support required (by others). Yoke mount features a yoke bracket that runs the full length of the fixture, the 4” octagonal junction box cover is centered on the yoke with auxiliary mounting holes. Horizontal and Run mount options use either a stem or hub canopy at each end to mount over a standard 4" octagonal junction box, auxiliary mounting holes are provided. INSTALLATION NOTES: During installation the contractor is responsible to use actual fixtures to ensure accurate mounting centers from one fixture to the next along the length of the linear run. Choose a mounting from below:

BRK | Bracket Mount

YOK | Yoke Mount  
RUN 3 | Continuous Run  
OAL | Specify Length of Run
