Super Anchor 1033-W 18" CRA Permanent Anchor Post – Commercial Fall Protection
The Super Anchor 1033-W 18" Anchor Post is a premier, pre-engineered permanent solution for flat and low-slope roofing systems requiring extra height for insulation clearance. This versatile Commercial Roof Anchor (CRA) is designed for multi-functional service, including single-user fall arrest, window-washing tie-back suspension, and use as a critical intermediate or end anchor for horizontal lifeline systems extending up to 240 feet. For projects with lower profiles or even deeper insulation needs, we also carry the Super Anchor 1032-W 12-inch Anchor Post and the Super Anchor 1042-W 24-inch Anchor Post variants.

Advanced Engineering and High-Tensile Performance
The 1033-W is manufactured to withstand extreme loads and features a loop top rated for 10,000 lbs of tensile strength. While the minimum required strength for fall arrest is 5,000 lbs, Super Anchor over-engineers these posts to ensure they meet the rigorous ANSI/IWCA I-14.1 standards for window washing and suspended maintenance. Standing 18 inches tall, this post is ideal for "warm roof" designs with thick insulation layers. The post is finished with an ASTM 123 Hot-Dip Galvanized (HDG) coating for maximum life expectancy, with premium 304 and 316 stainless steel options available for high-corrosion coastal environments.
Universal Compatibility and Installation Versatility
One of the most adaptable anchors in the 2026 market, the 1033-W installs seamlessly onto wood, metal, concrete, and structural steel decking. Every unit includes 40 self-drilling screws for immediate attachment to decking, though it also supports field welding, expansion bolts, or concrete embedment. Its design is compatible with nearly all modern roofing membranes, including TPO, EPDM, PVC, modified bitumen, and even green roof assemblies, ensuring a watertight integration when used with factory-supplied EPDM flashing.
Certified Safety and Long-Term Reliability
The Super Anchor 18" CRA Post is third-party engineered by DH Glabe & Associates and bears an individual serial number for complete 2026 traceability. It meets a comprehensive set of safety standards, including OSHA 1926.502, ANSI Z359.18-17, and CSA Z259.15:22. For facilities managers, this post offers a low-maintenance, state-of-the-art solution that ensures compliance throughout the building's roof system's entire lifespan.

Super Anchor 1033-W 18" Anchor Post FAQ
1. When should I choose the 18" post over the 12" model?
The 18" Super Anchor 1033-W is necessary when your roof assembly includes thick insulation (R-30 or higher) or ballast. The extra height ensures the loop remains accessible and can be properly flashed above the final roofing surface to maintain a watertight seal.
2. Can this post be used for window washing tie-backs?
Yes. The 1033-W is certified to meet ANSI/IWCA I-14.1 standards. Its 10,000-lb loop-top rating provides the essential safety factor required for suspended maintenance and window-washing tie-back applications.
3. What is the maximum span for a Horizontal Lifeline using these posts?
When used as intermediate or end anchors, these posts support HLL systems with total lengths up to 240 feet. However, specific rigging and cable tension requirements must be followed. Please see the CRA HLL Rigging Manual linked above for exact span engineering.
4. Is custom flashing required for TPO or EPDM roofs?
While standard EPDM flashing is available for metal roofs, membrane roofs (TPO/PVC) typically require target-patch flashing. To maintain your roof warranty, it is recommended to use the factory-supplied flashing boots designed specifically for the CRA series posts.
5. How many workers can tie off to a single 1033-W post?
For fall arrest, the 1033-W is rated for one user. When used as part of an engineered horizontal lifeline system, the system capacity is determined by the HLL design, which you can request via our HLL Quote Request Form above.
6. Can this be installed on a standing seam metal roof?
Yes. The CRA series is compatible with standing seam roofs when attached to the structural decking or framing. For non-penetrating options that attach to the seams, you might also consider our specialized Standing Seam Roof Anchors.
7. What is the required inspection interval for permanent posts?
- Annual Inspection: OSHA requires a documented inspection by a Competent Person at least once every 12 months.
- Post-Fall Inspection: If the anchor is subjected to fall arrest forces, it must be removed from service immediately and inspected by an engineer.
- Re-Certification: For window washing applications, local codes may require re-certification every 5 to 10 years.
