SSRA1 Nylon Standing Seam Roof Anchor Third-Party Testing
Independent testing on both 22- and 24-gauge steel confirmed the SSRA1 Standing Seam Roof Anchor's strength.
OSHA and ANSI require personal fall arrest anchorages to support 5,000 lbs. per attached worker. The SSRA1 was tested by two independent labs, one for each panel gauge it is approved for:
- 22-gauge steel, ANSI Z359.1-2007: Gravitec Systems, an ISO 17025-accredited lab, tested the SSRA1 to the section 4.3.6 anchorage connector qualification test with both cupped tip and nylon tip set screws (nylon tips torqued to 180 in-lbs), loaded parallel and perpendicular to the seam. It passed every test: 3,600 lbs. with no permanent deformation and 5,000 lbs. without breaking. View the Gravitec report
- 24-gauge steel, OSHA 1910.140: Using nylon tip set screws, Intertek found the SSRA1 met OSHA 1910.140(c)(8) static strength (3,600 lbs. held for 1 minute, parallel and perpendicular to the seam) and (c)(7) proof load (5,000 lbs. without failure). In a direct-tension proof test, the anchor reached an ultimate failure load of 14,500 lbs. View the Intertek report
- Corrosion, ASTM B117: salt spray tested for 696 hours. View the salt spray report
▶ SSRA1 Compatibility Overview
This Panel Compatibility Chart is provided only as a reference for what the SSRA1 will physically mount to. It does not determine the structural integrity of any roof system or seam. It is the Qualified Person's responsibility to verify structural suitability in the event of a fall. The SSRA1 fits over 95% of standing seam panels. It is approved only for 22- and 24-gauge steel and is not compatible with aluminum, zinc, copper, or other soft metals. Do not install on curved or tapered seams. Batten seams are OK as long as the set screws are not on top of the batten strip.
▶ Nailstrip Panel Warning
Nailstrip-style panels are approximately 50% compatible. Some seams are too wide at the base, which can allow anchor movement during installation. Treat compatibility lists as guidelines, not guarantees.
▶ Installer Responsibility
The employer and the designated Competent Person are solely responsible for evaluating, determining, and documenting the structural suitability of the supporting structure. The manufacturer assumes no responsibility for structural assessment or performance under load.
▶ Test Fit Recommendation
Perform a test fit with an RCT seam clamp or an SSRA1 anchor well before installation.
▶ Set-Screw Options
- Nylon-tip (installed on this anchor): 22- or 24-gauge steel (required on 24-gauge), torque to 180 in-lbs
- Cupped-tip: 22-gauge steel only, torque to 90 in-lbs (100 in-lbs when the anchor supports an SSRA3 plate)
- Use all 12 of one type. Never mix set screw types.
▶ Surface Impact
Minor seam dimpling and paint abrasion may occur. You can touch up scratches with a matching paint pen.
SSRA1 Nylon Standing Seam Roof Anchor Patented Non-Penetrating Design
The SSRA1 Standing Seam Roof Anchor features a patented design (US D629,679) with a solid 6061-T6 aluminum body secured by 12 nylon-tip stainless steel set screws.
This system provides a rock-solid attachment without damaging the seam. Unlike compression-style anchors that rely on plates to squeeze the seam with high torque, the SSRA1's set screws grip the seam directly to prevent sliding during impact and deliver consistent holding power at much lower torque settings.
Each SSRA1 comes standard with a 5,000-lb-rated forged D-ring for single-worker tie-off. The universal-fit SSRA1 anchor body adapts to more than 500 standing seam panel profiles, including T-seams, bulb seams, SnapLok, MR-24, single lok, and double lok, without requiring reassembly.
The SSRA1 has a unique removable D-ring, making it compatible with adapter plate components. The SSRA2 Adjustable Roof Jack Adapters mount on top of the SSRA1 to support 2x10 walkboards. Contractors can use the SSRA3 Anchor Plates connected to SSRA1 anchors to create temporary 100-foot horizontal lifeline systems.
SSRA1 Nylon Standing Seam Roof Anchor Benefits for Fall Protection
- Weighs only 4.5 lbs. and is just 12 in. long, yet is rated to 5,000 lbs.
- Installs in minutes with a micro torque wrench and 3/16" hex bit socket
- The universal-fit design works on over 500 standing seam panel profiles
- Nylon-tip set screws perform better than cupped tips on 24-gauge steel and are the required set screws for 24-gauge panels
- Non-penetrating installation protects roof warranties and watertight performance
- Tested with loads both parallel and perpendicular to the seam, so it protects workers on either side of the anchor
- Made in the USA from durable aluminum and stainless steel, salt spray tested to ASTM B117 for 696 hours
- Clean, low-profile installation reduces tripping hazards on the jobsite
- Includes a Limited Lifetime Warranty
SSRA1 Nylon Standing Seam Roof Anchor Applications
The SSRA1 Standing Seam Roof Anchor is a versatile solution for many safety applications.
Workers can use it to attach roof jacks for 2x10 wooden walkboards, self-retracting lifelines (SRLs), horizontal lifelines, and ladder anchoring. Workers using SSRA1 anchors must use inline shock absorbers or shock packs. The SSRA1 Nylon ships with nylon-tip set screws installed, which work on 22-gauge panels and are required on 24-gauge panels. Cupped-tip set screws are available separately for 22-gauge steel. Each anchor supports one worker with a maximum loaded weight of 310 lbs., including tools and equipment.
How to Install the SSRA1 Nylon Standing Seam Roof Anchor
Installation takes about 2 minutes per anchor. Tools: an inch-pound torque wrench (1/4" drive), a 3/16" hex bit with a pivoting bit holder, a 9/16" socket, and a screw gun or ratchet.
- Confirm the panel. Check your profile on the Panel Compatibility Chart. The nylon-tip set screws on this anchor work on 22-gauge steel and are required on 24-gauge steel. Never mix screw types.
- Check the top bolts. Before going up, torque-check the 2 top bolts to 90 in-lbs with a 9/16" socket.
- Check the set screws. Confirm all 12 nylon tips are present and undamaged, then back the set screws out far enough for the body to seat over the seam.
- Seat the anchor. Set the screws on one side in a straight row about halfway across the clamp opening, then tighten the opposite side, keeping the anchor centered and flat on the seam. Use a screw gun on a clutch setting or a ratchet. Never use an impact gun.
- Torque to spec. Do the final torque with the torque wrench: nylon tips 180 in-lbs. Torque-check all 12 screws twice, because some seams stretch.
- Connect. Attach one self-locking connector to the D-ring with an energy-absorbing lanyard or SRL. Install the anchor at least 6 ft. from any roof edge.
SSRA1 Nylon Inspection Requirements
The user inspects the SSRA1 before each use. A Competent Person other than the user completes a formal inspection at least every 6 months and logs it in the owner's manual and on the device label. Free inspection forms and resources are available.
- No corrosion, cracking, or deformation of any component
- No cross-threaded set screw holes or set screws
- All 12 nylon tips present, not crushed or badly deformed; replace worn set screws
- Top bolts and D-ring tight and undamaged
- Labels present and legible, with the date of first use recorded
Remove the anchor from service after any fall arrest or if it fails inspection. The Limited Lifetime Warranty requires 6-month inspections.

SSRA1 Nylon Standing Seam Roof Anchor Frequently Asked Questions
What is the SSRA1 Nylon standing seam roof anchor?
The SSRA1 Nylon is the SSRA1 standing seam roof anchor fitted with 12 nylon-tip stainless steel set screws. It is a 4.5 lb, non-penetrating aluminum anchor that provides one worker with a 5,000-lb-rated fall-arrest anchorage on 22- or 24-gauge steel standing seam roofs without drilling the roof.
When do I need nylon-tip set screws instead of cupped-tip?
In our comparison testing, nylon-tip set screws gripped 24-gauge steel better than cupped-tip set screws, so we completed the full independent testing on 24-gauge panels with nylon tips, and nylon tips are required on 24-gauge panels. On 22-gauge steel, you can use either nylon tips or cupped tips. Use all 12 of one type and never mix them.
What torque do nylon-tip set screws require?
Torque nylon-tip set screws to 180 in-lbs with an inch-pound torque wrench and a 3/16" hex bit. Torque-check all 12 screws twice, because some seams stretch. Never use an impact gun.
Is the SSRA1 Nylon OSHA- and ANSI-compliant?
OSHA does not certify products. Using nylon-tip set screws on 24-gauge steel, Intertek found the SSRA1 met OSHA 1910.140(c)(7) and (c)(8). On 22-gauge steel, it passed the ANSI Z359.1-2007 section 4.3.6 anchorage connector test with nylon tips at Gravitec Systems, an ISO 17025-accredited lab. Both reports are on our testing page.
Which roofs does the SSRA1 Nylon fit?
It fits more than 500 standing seam profiles in 22- and 24-gauge steel, including T-seam, bulb seam, single lock, double lock, SnapLok, and Butler MR-24. It is not for aluminum, zinc, or copper panels, or for curved or tapered seams. Batten seams work as long as the set screws are not on top of the batten strip. About 50% of nailstrip panels are compatible. Check your exact panel on our Panel Compatibility Chart.
Are the nylon tips permanent?
No. Nylon tips are consumable. Inspect them before every use, and replace the set screws if a tip is missing, crushed, or badly deformed. Replacement 12-packs of nylon-tip set screws are available.
Can I attach an SRL, walkboards, or a horizontal lifeline to the SSRA1 Nylon?
Yes. Attach one self-locking connector at a time to the D-ring, with an SRL or energy-absorbing lanyard. With the D-ring removed, SSRA2 Adjustable Roof Jack Adapters support 2x10 walkboards, and SSRA3 Anchor Plates across SSRA1 anchors create a temporary 100 ft. horizontal lifeline.
