Radius Elbow Vanestones

Large elbows and radius fittings may need vane support/vanestones so turning vanes stay secure and aligned.

Stop if

• This elbow has turning vanes/vanestones. Do we verify vane spacing and attachment before closing it up?

Watch out

• Do not leave unsupported loose vanes or install vanes backwards.

Check

• Confirm vane spacing/support, attachment, airflow direction, and whether vanes are required by detail.

Steps

• Identify whether this is normal ductwork or a controlled/special condition.
• Confirm vane spacing/support, attachment, airflow direction, and whether vanes are required by detail.
• Get the current drawing/detail/spec/submittal before changing routing, material, access, or support.
• Bring photos, location, and what you checked to the foreman before closing or covering the work.
