Cush-A-Block® CBN-DSFW Fixed Width Duct Support

---

The Cush-A-Block® CBN-DSFW Series is designed specifically for supporting duct work. The cross beam provides easy size adjustments. 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-DS is based on the length of strut used to support the pipe
