1090-GBS Bolt-On Loop Top with 5/8 Inch Stud
The Super Anchor 1090-GBS is a cast, hot dip galvanized loop top with a 1-3/8 inch inside diameter loop and a grade 5, 5/8 x 2 inch stud bolt with lock nut and washer. It threads a 10,000 lb tensile rated loop top onto threaded-top anchors and bolts through the center hole of the Super Anchor 1207 standing seam plate per Fig. 6 of the SSCA manual.
What is included: the cast loop top with its grade 5 stud bolt, lock nut, and washer; the 1207 plate and cable are sold separately. At about 1 lb, the 1090-GBS is the lightest way to put a CRA style loop top where you need one: on a threaded-top anchor or centered on a 1207 plate for non-penetrating standing seam roof anchorage. The loop accepts snaphooks, carabiners, and SAS HLL end anchor components with 3,600 lb gate strengths per the CRA manual connector specifications.
Who Needs This Product
The 1090-GBS is for crews that need a compliant loop top connection point on hardware that ships without one. Metal roofing contractors bolt it through the center hole of the 1207 standing seam plate to create a loop top anchor that clamps to the seams without penetrating the roof, and it also threads onto Super Anchor threaded-top anchors. The loop serves a single worker at up to 340 lb including tools for fall arrest, work positioning, and fall restraint with a maximum 6 ft free fall, with the anchorage itself required to support 5,000 lb or 2 times the intended load per OSHA 1910.140. Every worker wears a full body harness with components meeting current OSHA, ANSI, or CSA standards.
Features
10,000 lb cast loop
The cast loop top is rated to 10,000 lb minimum tensile strength per the CRA documentation, with a 1-3/8 inch inside diameter opening.
Grade 5 stud with hardware
A 5/8 x 2 inch grade 5 stud bolt with lock nut and washer installs with common hand tools.
Fits the 1207 center hole
Bolts through the center hole of the 1207 standing seam plate per Fig. 6 of the SSCA manual for non-penetrating metal roof anchorage.
Threaded-top anchor upgrade
Threads onto Super Anchor threaded-top anchors to convert them to loop top service.
Hot dip galvanized
HDG coating protects the casting; connector abrasion wear cleans up with 2 coats of cold zinc spray per the CRA manual.
Compatible connectors
Accepts snaphooks, carabiners, and SAS HLL end anchor components with 3,600 lb gate strengths; connectors must rotate freely and never share the loop.

The loop top is only as strong as what it bolts to. The 1090-GBS itself carries a 10,000 lb tensile rating, but the assembled anchor is limited by the anchorage below it, which must support 5,000 lb or 2 times the intended fall protection load per OSHA 1910.140. Install the stud with the lock nut and washer fully engaged, never attach two connectors to one loop, and load the loop only in the directions specified by the CRA manual.

OSHA 1926.502 / 1910.140
Assembled anchorages meet construction criteria with 5,000 lb structural support requirements.
CSA Z259.15:22 Type A/T
Canadian anchorage connector conformity for cross-border crews.
Third Party Engineering
CRA anchor systems carry Intertek lab reports and engineering by DH Glabe and Associates.
Typical Applications
Installation Overview
Fig. 6 of the SSCA manual and the CRA manual loop top figures cover the details. The essentials:
- Confirm the anchorage below the loop supports 5,000 lb or 2 times the intended fall protection load per OSHA 1910.140.
- For standing seam service, install the 1207 plate on the seams per the SSCA manual, then bolt the 1090-GBS through the plate center hole.
- Thread the 5/8 x 2 inch grade 5 stud into a threaded-top anchor, or through the plate, with the washer seated and the lock nut fully engaged.
- Connect one snaphook or carabiner with a 3,600 lb gate strength; the connector must rotate freely on the loop.
- Never attach two connectors to one loop top, and apply loads only in the directions the CRA manual specifies.
- Inspect the loop, stud, lock nut, and the supporting anchorage before each use.
Inspection and Retirement
Inspect before installation and each use, with documented annual inspections of the assembled anchorage. Remove the loop top from service when any of the following apply:
- The loop is bent, cracked, gouged, or deformed.
- The stud, lock nut, or washer is damaged, loose, or missing.
- Threads are stripped or corroded.
- Rust that does not clean up with 2 coats of cold zinc spray.
- A connector does not rotate freely on the loop.
- The loop was subjected to a free fall or the supporting anchorage is damaged.
Tag anchors removed from service to prevent further use until inspected by a qualified or competent person.
