Purlin Anchor
Groxx Purlin Anchor | GGRXPA789
Roof Purlin Anchor Bolt for Corrugated Roof Profile (Small)
The Groxx Purlin Anchor (Model Number: GGRXPA789) is a premium, industrial-grade personal fall protection component engineered to attach directly to structural roof purlins through corrugated sheet profiles. Serving as a permanent single-point anchorage connector, this high-tensile hardware provides dependable fall-arrest security for technicians executing high-altitude roof maintenance, inspections, and industrial staging tasks.
Core Performance Features
Direct Structural Purlin Anchoring: Engineered as a dedicated single-point anchor designed to be fixed directly into the building’s underlying roof purlins through corrugated sheet crowns to create a permanent, heavy-duty anchorage zone.
Vital Fall Protection Interface: Specifically optimized to serve as a reliable tie-off point for personal fall arrest systems (PFAS), shock-absorbing lanyards, and vertical lifelines.
Watertight Joint Sealing: Outfitted with an integrated rubber washer system to ensure correct mechanical installation and render the penetrated corrugated roof joint fully leak-proof against rainwater entry.
Multi-Directional Strength Capacity: Built with structural reserve limits that deliver a minimum breaking strength of 15 kilonewtons across both the horizontal and vertical load vectors (X and Y axis direction paths).

Regulatory Compliance and Standards
The GGRXPA789 structural purlin anchor assembly is thoroughly verified and certified to comply with primary international rigging and height safety engineering criteria:
EN 795:2012 TYPE A: Conforms to European standards for permanent single-point anchor devices fixed securely to structural building substrates.
AS/NZS 5532:2013: Conforms to Australian and New Zealand manufacturing safety mandates evaluating the performance integrity of single-point anchor devices under dynamic and static testing profiles.
The Groxx Advantage
Marine-Grade 316 Longevity: Forged entirely from polished 316 Stainless Steel, the structural eye-bolt and nut assembly offers exceptional protection against pitting and atmospheric degradation. This ensures the anchor point remains structurally sound over years of exposure to harsh rooftop weather and coastal salt air.
Neoprene Leak Defenses: The integrated Neoprene Rubber washer acts as a flexible, heavy-duty barrier that compresses flush beneath the metal saddle block. This design dampens building vibrations while sealing the 30 mm installation opening completely against industrial leaks and rust tracking.
True Multi-Axis Load Protection: While standard hardware eye-bolts can bend or shear if pulled sideways, the GGRXPA789 is engineered to withstand a massive 15 kN breaking force in both the X and Y coordinates. This ensures complete structural stability regardless of which way a worker moves or falls along the roof line.
