ACRO 12090 Parapet Wall Guardrail System - Non-Penetrating Fall Protection for Flat Roofs

The ACRO 12090 Parapet Wall Guardrail System is a no‑penetration fall protection solution engineered for flat roofs with parapet walls. Made up of a bracket and post, it installs securely by clamping onto parapets ranging from 4 to 24 inches wide using an adjustable hand screw, eliminating the need to penetrate building surfaces. The system includes a guardrail post holder that accepts standard 2×4 lumber cross‑rails—no tensioning required—and supports setup from inside the parapet. Lightweight (approximately 18–19 lb per unit), easily movable without full disassembly, and compliant with OSHA requirements for spacing and height, the unit is an efficient and durable safety option for contractors.
