Supports & Hangers · Expanded master guide
Traditional Hangers & Supports
Ten expanded field guides for traditional hangers and supports: straps, band hangers, trapezes, shared racks, riser supports, wall brackets, rooftop stands, insulation shields, spring isolation, and seismic bracing.
The support carries the load—not the duct joint.
Verify the attachment, substrate, load, hardware, spacing, insulation protection, rooftop detail, vibration control, and seismic design before installation.
