Deadweight Anchor Points for Roofs

When you need compliant fall protection on a flat roof but cannot risk drilling into the structure, traditional rigid post anchors are out of the question. Our freestanding deadweight anchor systems provide a safe, OSHA-compliant alternative that requires zero roof penetration.

Designed for roofs with a pitch of 5 degrees or less, this system relies on an engineered deadweight design to deliver active fall protection without compromising your roof's integrity. Because it eliminates the need to puncture the membrane, you completely avoid the leaks, structural damage, and voided warranties that come with fixed-post installations.

While these systems are heavy-duty by design, they are built for practical deployment. No individual component weighs more than 56 lbs, and every weight features built-in handles, allowing your crew to transport and assemble the system on-site without heavy machinery.

Ultimately, these non-penetrating tie-off solutions provide reliable active work restraint without a permanent structural commitment. They are highly effective for facilities requiring localized "spot protection" in just four to five locations on a rooftop. However, if your facility requires expansive, full-roof coverage, traditional rigid post anchor systems tend to be the more economical choice.

 

Other Rooftop Safety Solutions

Why are integrated handles a safety feature rather than just a convenience? 

Handles ensure that workers can transport the 56 lb components safely without dropping them on their feet or the roof membrane: preventing injuries and accidental damage during the setup process. 

Can this system be used on a roof with loose stone or gravel?

 Yes: but the stone chipping or gravel must be brushed back so the rubber weights make direct: 100% contact with the roof membrane or concrete to ensure maximum suction. 

What are the risks of using lanyards with high arresting force? 

These anchors are engineered for use with lanyards that have a maximum arresting force of 900 lbs. Using a lanyard that exerts higher forces may cause the anchor to slide across the roof surface during a fall. 

How do environmental factors like UV exposure affect the rubber weights?

 High UV exposure can cause rubber to become brittle over time. We use specialized: bonded rubber designed for harsh environments: but the weights should be inspected annually for cracking that could reduce friction. 

What happens to the anchor if it successfully arrests a fall? 

After an impact: the system must be immediately removed from service. The rubber suction cups and the galvanized steel components must be inspected by a Qualified Person to ensure no sliding or structural deformation occurred. 

Who is qualified to determine if my roof substrate can support a deadweight anchor?

 A Qualified Person: such as a structural engineer: must verify the roof can handle the concentrated 600+ lb load of the assembly. This is especially critical for older buildings or lightweight roof decks.

Compliance

  • OSHA 1910.140 and 1926.502: Anchors are engineered to support a 5,000-pound static load or be designed as part of a complete engineered system with a 2:1 safety factor. 
  • ANSI Z359.18 Certification: Every unit is tested for dynamic and static strength: ensuring it can withstand the forces of a fall without sliding across the roof surface. 
  • Material Science (Galvanization): Steel components are hot-dipped galvanized to BS EN ISO 1461 to resist environmental corrosion and ensure a multi-decade service life. 
  • Surface Grip Technology: Weights are bonded with rubber and feature over 100 molded-in suction cups to provide maximum friction in both wet and dry rooftop conditions. 
  • Qualified Person Oversight: System layout and usage must be approved by a Qualified Person to ensure the specific roof substrate can handle the concentrated deadweight.

Easy to Install

This freestanding roof anchor system can be deployed quickly, delivering OSHA-compliant fall protection exactly where it is needed. The included hex key and torque bar are the only tools required for assembly. Setup is straightforward, completely eliminating the need for specialized labor or complex tools.

Versatile Fall Protection

These deadweight anchors can be configured for either fall arrest or fall restraint. As a fall arrest system, it provides a compliant anchor point for a single worker. In the impact of a fall, the heavy-duty rubber coating around the base weights spreads the load over a 20-square-foot area, protecting both the worker and the roof deck. Alternatively, it can be set up as a fall restraint system for up to two workers, keeping them safely away from the roof edge.

Adaptable to Your Structure

These freestanding anchors are the perfect solution when traditional, rigid post installations are impractical or forbidden by property owners. The system is fully tested and approved for a wide variety of flat roof types, including single-ply membranes, mineral felt, concrete, and asphalt with stone chippings (brushed roofs). It provides reliable, slip-resistant performance in both wet and dry conditions.

NON-PENETRATING

Because the system rests entirely on top of the roof surface, it requires zero drilling or puncturing. This protects your facility from costly leaks and keeps your manufacturer roof warranties fully intact.

Durable

Hot-dip galvanized to international corrosion standards (BS EN ISO 1461), this deadweight anchor system is engineered to last for decades. It resists severe weather and harsh industrial environments without degrading, ensuring a long and reliable service life.
