DynaRound Slimline Warning Lines

Tough, weather-resistant heavy duty or light duty warning lines to help ensure rooftop safety

DynaRound Slimline Warning Lines are available as heavy duty (HD) and light duty (LD) systems.  Both include highly visible yellow pennants to protect workers near rooftop edges.

DynaRound HD Warning Lines are a permanent system that provide a visual warning of at-risk areas.  They are designed to withstand years of use, even in harsh climates.  The standard system includes three stanchions and three heavy-duty, galvanized, weighted bases; steel cable; and rigid, plastic pennants.   

A foldable warning line that can be set up quickly, DynaRound LD Warning Lines are to be used in temporary warning line applications.  The standard LD system has three folding stanchions with bases (with optional rubber feet attachments) and 100 feet of flags.

Both systems meet numerous safety requirements, including those established by OSHA, OH&S and Alberta OSHA 2009.

Available through Tremco Roofing and Building Maintenance, this safety solution was designed and manufactured by Fibergrate Composite Structures.  Click here for our installation manual.
