RC Concrete Roof Anchor Post, 12, 18, and 24 inch
The Frontline RC is a commercial anchor post for concrete structures, available in 12, 18, and 24 inch heights (RC12, RC18, RC24) to clear insulation, roofing buildup, and membrane details. The U-rod connection point at the top of the post accepts an extensive range of connecting devices - self-retracting lifelines, shock absorbing lanyards, and vertical and horizontal lifelines - for fall arrest, fall restraint, work positioning, and rescue operations.
Each post is built from ASTM rated steel and hot dip galvanized to ASTM requirements, so it withstands the toughest jobsites and weather, indoors or out. The anchor carries a 5,000 lbf tensile strength and a 310 lb maximum user capacity per the spec sheet, conforms to ANSI Z359.18 and ANSI A10.32, aligns with OSHA 1926 and 1910, and has been tested by an independent third-party lab accredited to ISO/IEC 17025. Pair it with the RC-BKRPLT backer plate for through-bolt installations.

Who Needs This Product
This product is a fixed anchorage connector - the anchor point of a personal fall arrest, restraint, positioning, or rescue system on concrete roofs and structures. Building owners, roofing contractors, and facade access designers install RC posts where crews need permanent, weather-resistant tie-off. Each worker still needs a full body harness and a compatible connecting device attached to the U-rod.
Features
Three post heights
12, 18, and 24 inch heights clear different roof buildups - choose the post that keeps the connection point above the finished surface.
Multi-application rating
Designed for fall arrest, fall restraint, work positioning, and rescue operations from one anchor.
Hot dip galvanized
ASTM rated steel with an ASTM rated hot dip galvanized finish shrugs off weather, indoors or outdoors.
Broad connector compatibility
Works with SRLs, shock absorbing lanyards, and vertical and horizontal lifelines.
0.625 inch U-rod
A generous welded connection point that accepts carabiners and snap hooks with ease.
Independently tested
Performance verified by a third-party laboratory accredited to ISO/IEC 17025.

The structure carries the load. The concrete structure and anchorage hardware must be verified by a qualified person for the intended fall protection load before use. One worker per anchor at 310 lbs maximum per the spec sheet - follow the user manual for fastening requirements, use the RC-BKRPLT backer plate where the installation calls for through-bolt mounting, and calculate fall clearance before tying off.

Typical Applications
Installation Overview
Follow the manufacturer's manual. The sequence below is an overview only.
- Inspect. Check the post, base plate, U-rod, welds, and finish before installation.
- Verify structure. Have a qualified person confirm the concrete structure carries the intended fall protection load.
- Select the height. Choose RC12, RC18, or RC24 so the U-rod clears the finished roof buildup.
- Fasten. Anchor the base plate to the structure with the fastening method and hardware the manual specifies - including the RC-BKRPLT backer plate for through-bolt installations.
- Torque and verify. Torque all hardware to specification and verify the installation before first use.
- Connect. Attach the connecting device to the U-rod and verify fall clearance before work begins.
Inspection and Retirement
Inspect before each use, with a documented competent-person inspection at least every 6 months. Pull the equipment from service for any of the conditions below.
- Post and base plate: bending, cracks, or deformation.
- U-rod: bending, nicks, gouges, or wear at the connection point.
- Welds: cracking, corrosion, or any visible defect.
- Fasteners: corrosion, looseness, or loss of torque at the base.
- Galvanized finish: damage that exposes bare steel; markings missing or illegible.
Retire the anchor immediately after any fall arrest event, any deformation, weld damage, or any condition where it cannot be verified as safe for service.
