KATTGUARD™ Modular Aluminum Roof Guardrail Systems

When it comes to preventing passive falls, guardrails are the bread and butter of open rooftops. They’re an essential component for any permanent roof that has potential fall hazards and are often the last line of defense. That means they must be structurally sound and dependable. For that reason, we only use strong materials and reliable mounting mechanisms designed for the task. We’ve also made sure they’re easy to set up with lightweight construction and modular designs to suit any size or shape of roof.

Guardrails can come in various configurations and styles, and they may include additional components like walkways, toe-boards, mats and warning systems. Most models are available in a mill finish and safety yellow along with custom colors.

The KATTGUARD™ roof guardrail systems include the internal and external roof mount guardrail as well as metal, surface mount and non-penetrating guardrails. As the names imply, internal and external models work on either side of the roof, while metal guardrails are designed to attach to metal roofs. Non-penetrating guardrails offer a free-standing solution that is compliant with Occupational Safety and Health Administration (OSHA) standards. Finally, surface mount guardrails provide stability for sloped rooftops, high winds, ice and snow.

Other fall protection products that can help you create comprehensive roof safety include:

  • Walkway systems: Sleek aluminum finishes pair well with just about any rooftop, and these walkway systems provide a convenient pathway for workers to use to cross a roof. KATTGUARD® guardrails work well on either side of a walkway. They also come with a bar for added stability during use.
  • DukMat™ walkways: DukMat™ adds safety to walkway systems with its high-grip surface that helps prevent falls and slips. You can trust it to stand up to strong weather with UV resistance, a drainage grid and stability in winds up to 60 miles per hour. It also keeps the roof membrane protected from foot traffic.
  • Warning line systems: Bright yellow posts provide a highly visible alert for low-traffic and low-risk areas that still contain a fall hazard. These systems are a great way to reduce costs but provide necessary safety where appropriate. You can also combine them with KATTGUARD™ guardrails for fully compliant rooftops.


Whatever your rooftop calls for, KATTGUARD™ systems only use reliable materials and tried-and-true construction practices. That’s what makes FIXFAST USA a trusted supplier of rooftop safety tools.
