ROOF DUCT SUPPORT SYSTEMS
The Roof Duct Support Systems are designed to support ducting, cable tray and piping at any specified height or width. The supports are designed for installation without roof penetrations, flashings, or damage to the roofing material, and can be used for virtually any roofing system - from flat roofs to roofs sloped up to 2 in 12. The supports should be spaced according to the specifications.
Seismic and High-Wind applications are also available for the system.

- Layout isolation pads, (provided by contractor), according to the design and layout.
- Place bases on isolation pads.
- Insert the legs of duct support into bases and attach with 2-1/2” bolt and 1/2” nut.
- Space out pipe supports according to specifications. This should be done before any weight is supported.
- *Attach horizontal bracing to the legs of duct supports (approximately 3/4” of the way up the height of the support), with 3” bolt and 1/2” nut.
NOTE: If double or triple bracing is required, designated locations will be marked on support legs.
- Adjust width up to bottom of duct.
- Make sure the duct and supports are level, both vertically and horizontally, and proper spacing is maintained per design specifications.
