Double Wall Vertical Ceiling Support
1. The vertical ceiling support system is used when a wall support cannot be used or installed.
2. After all-thread has been installed, install Unistrut with provided 1/2” hardware. Install floor support
plates to Unistrut with 3/8” hardware.
3. When installing duct/chimney, make sure that the floor support fastener band and floor support are
located under the V-band. Refer to Table 6 for vertical spacing specifications.
4. Secure the floor support fastener band to the outer shell using the 5/16”-18 x 1-1/2” self-drilling screws.
Use the guide holes to locate the shell center. Install screw into center, center left and center right. A
minimum of 18 screws must be used on each side of the duct/chimney.
NOTE: Supports must be rotated so that all thread is attached directly to the ceiling. DO NOT
ATTACH ALL THREAD FROM ONE UNISTRUT TO ANOTHER.
