Lateral & longitudinal seismic bracing assemblies for rectangular and round HVAC ductwork — sized to the post-insulation duct dimensions and engineered to resist seismic action from any horizontal direction.
HVAC duct seismic bracing restrains rectangular and round ductwork against earthquake-induced movement. Lateral braces resist side-to-side displacement, longitudinal braces resist movement along the duct axis, and four-way bracing handles both at key locations.
All members use finished, compatible components — channel, gusset connectors, swivel attachments and anchors — for fast, repeatable installation. Spacing and load capacity are calculated to the carried duct weight and code-required seismic forces.
Engineered assemblies use these compatible components from a single factory.
