AL-311 GR1 Freestanding EdgeGuard Guardrail Kit

The PGTEC GR1 is a freestanding EdgeGuard guardrail kit that provides compliant fall protection along flat roof edges without drilling, penetrating or sealing the roof membrane. The system stands on heavy counterweight base blocks placed on the roof, and carries galvanized steel posts, two horizontal rails and a toe board along the edge, finished with navy-blue end caps for visibility. Because it is fully freestanding, the GR1 can be installed, relocated and removed in minutes by a two-person crew, making it the standard choice for temporary construction phases, seasonal roof work, rental fleets and facilities that cannot allow penetrations in waterproofing. The galvanized steel rails and posts resist weathering, and the counterweights are sized so the rail meets edge-protection load requirements even in high-wind locations. The kit is modular: straight sections, corners and gates connect with simple clamps, so any roof perimeter can be enclosed. Guards of this type are used on flat industrial and commercial roofs, around skylights and roof openings, and along loading edges where a permanent parapet does not exist. Supplied as a numbered kit with base blocks, posts, rails, toe boards and fixing clips, the PGTEC GR1 gives contractors and building owners a non-penetrating, reusable edge guard that complies with working-at-height edge-protection standards and keeps roof crews safe without touching the waterproof layer.
