ACRO 12045 - Vertical Guardrail System

The ACRO 12045 Vertical Guardrail System bracket and post is engineered for fall protection on low-pitch roofs, parapet walls, skylights, stairwells, elevator shafts, and other rooftop edge hazards. It mounts securely to vertical surfaces—such as parapet walls, header beams, or framing—using screws or anchors and supports 2×4 construction lumber cross-rails for guardrail setups spaced up to 8 ft apart. The system design was upgraded to accommodate 2-inch parapet caps and drip edges and features powder-coated safety-yellow steel for durability and visibility.

Key Features:
• Attaches over parapet walls or vertical structures without obstructing roofing work
• Accommodates cross-rails of 2×4 lumber for quick guardrail build-out
• Recessed post holder clears 2″ parapet caps and drip edges
• Bracket supports OSHA-compliant spacing up to 8 ft between posts
• Powder-coated steel construction for durability and visibility

• Part: ACRO 12045 – Bracket & Post

• Compatible material: 2×4 construction-grade lumber for cross rails

• Mounting surfaces: Parapet walls, header beams, joists, trusses, wall framing

• Attachment options: Screws to wood; lag bolts through decking; Tapcon anchors to masonry

• Maximum spacing: 8 ft between guard posts

• Post clearance: Recessed 2″ for parapet/drip edge compatibility

• Compliance: Meets OSHA 1926.502 & 1910.23 regulations

• Finish: Safety yellow powder-coated steel

• Weight: Approx. 7 lb

• Attachment plate dimensions: 9.5″ × 5.25″

• Fasten the bracket to a structurally sound vertical surface (e.g., parapet wall) using screws or anchor bolts rated for at least 200 lb pull-out load.
• Insert the guardrail post into the recessed holder above the bracket, ensuring seating and clearance of parapet caps/drip edges.
• Slide a standard 2×4 into the post holder slots to form cross-rail. Overlap ends of lumber at adjacent posts and secure with nails as required.
• Maintain maximum spacing of 8 ft between posts to comply with OSHA spacing requirements.
• Inspect entire assembly before use; ensure all components are seated and secure.
• For disassembly, remove cross-rail, pull post from bracket, and detach bracket from wall.
