Triangle Duct Markers

Triangle Duct Markers

identify equipment & air flow
in the ductwork systems.

Much like pipe marking labels, triangle duct markers are essential for alerting employees of the contents of the duct. These labels use the same ANSI color scheme that pipe marking labels follow to promote continuity in all facility labeling efforts. Not only that, but they also simultaneously work to denote the flow direction of the duct’s contents.


Made of durable adhesive vinyl, these triangle duct markers are made to last for five plus years without the need for replacement. If you don’t see a triangle duct marker you like here, call us at 1-886-777-1360 or send an email to info@creativesafetysupply.com! We’d be happy to help you create custom labels at no extra cost.
