Which low-clearance bar fits your application?
When choosing a low-clearance warning bar, start with where it will be installed and how drivers approach the restricted area. Suspended bars work well when you have an overhead structure available, while freestanding systems provide a warning point where there is nothing suitable to hang from. We offer fixed and swinging freestanding configurations, along with suspended bars in several diameters and lengths.
Visibility and messaging are the next considerations. Standard yellow bars provide a highly visible physical warning, while custom-imprinted versions let you add clearance heights or other short messages directly to the bar. Several models also offer different bar and lettering colors, which can help match existing traffic-control standards or make the warning easier to distinguish in a particular environment.
