Wall bracket for horizontal duct

Before you start

• Confirm the approved support detail, actual duct weight, support spacing, attachment substrate, hardware size, corrosion protection, and any insulation, seismic, vibration, or rooftop requirements before installation.
• Confirm wall substrate, bracket projection, cantilever load, anchor type, duct width, wall clearance, corrosion protection, and roll restraint.
• Verify the wall is structural and suitable for the anchor.
• Inspect brackets, welds, holes, and hardware.

Lay it out

1. Mark bracket elevations and structural attachment points.
2. Keep supports clear of duct joints and access doors.
3. Provide enough wall clearance for insulation, sealing, and maintenance.

Set and support it

1. Install brackets into approved structural substrate.
2. Level brackets as a set along the wall.
3. Add the approved saddle or cross member.
