CBN-BR Series | Cush-A-Block Bridge Support with Channel
Cush-A-Block® CBN-BR Bridge Series
Like all of the Cush-A-Block® supports, the CBN-BR Bridge Rooftop Supports are perfect for supporting natural gas and refrigeration piping systems, cable tray, electrical conduit, multiple lines, HVAC equipment, and many other applications.
The CBN-BR Series provides a longer mounting surface with strut lengths from 28" (0.7m) up to 60" (1.5m). Custom lengths are available upon request. Standard strut mount pipe clamps are used to secure the pipes.
Uniform load capacity for the Cush-A-Block® CBN-BR is based on the length of strut used to support the pipe
