MEGA Swivel 5K Stainless Steel Concrete Anchor
The Frontline COM345K-SS is the corrosion resistant member of the MEGA Swivel family, machined in 316 stainless steel for marine, coastal, wastewater, and chemical environments where zinc plated hardware corrodes out of service. The swivel ring design lets the D-ring rotate a full 360 degrees and flip back and forth 180 degrees, keeping the lifeline aligned with the worker, while the patent pending key lock design keeps the D-ring seated and locked in its swivel housing under heavy loads.
Like its plated siblings, the stainless anchor body is reusable: install it in sound structural concrete, work the area, then remove it and relocate with a new COM345K-SSRB stainless replacement bolt. Rated at 5,000 lbf tensile strength with a 1,000 lb working load and 310 lb user capacity. The spec sheet claims ANSI Z359.1-2007 and Z359.7-2011, OSHA CFR 1926.502 and 1910.140, and EN 795.

Who Needs This Product
This product is a reusable stainless steel concrete anchorage connector. It provides the anchor-side tie-off point of a personal fall arrest or fall restraint system in corrosive environments: docks, treatment plants, chemical facilities, and coastal structures. Pair it with a full body harness and an energy-absorbing lanyard or self-retracting lifeline. It is not a complete fall protection system on its own, and a competent person must verify the concrete substrate before use.
Features
316 stainless steel construction
Marine grade 316 stainless resists chlorides, washdown chemicals, and salt atmosphere that destroy plated anchors.
360 degree swiveling D-ring
The D-ring rotates 360 degrees and flips 180 degrees, keeping the connecting device aligned with the worker as they move.
Patent pending key lock design
Keeps the D-ring seated and locked into its swivel housing, preventing the steel from spreading outward during heavy loads.
Reusable anchor body
Remove the anchor and relocate it across the facility. Each new anchoring point requires a fresh COM345K-SSRB stainless bolt.
Independent test report
A dedicated COM345K-SS test report is published alongside the spec sheet and manual for submittal packages.
Multi-orientation installation
Works on vertical, horizontal, and overhead concrete: walls, columns, ceilings, and structural decks per the user manual.

The bolt is single-installation. The stainless anchor body is reusable, but the concrete bolt must be replaced with a new COM345K-SSRB stainless bolt every time the anchor is moved to a new anchoring point. Never reinstall a used bolt, never substitute a plated bolt in a corrosive environment, and only install in sound, cured structural concrete per the Frontline user manual.

Typical Applications
Installation Overview
Follow the manufacturer's manual. The sequence below is an overview only.
- Select. Have a competent person choose sound, cured structural concrete clear of cracks, spalls, and edges, per the manual's substrate requirements.
- Drill. Drill the hole to the diameter and depth specified in the Frontline user manual for the COM345K-SS bolt.
- Clean. Blow out and brush the hole so dust and debris do not compromise the bolt's grip.
- Install. Seat the anchor and tighten the stainless concrete bolt to the torque specified in the manual.
- Verify. Confirm the anchor is fully seated, the D-ring swivels freely, and the installation matches the manual before connecting.
- Relocate. To move the anchor, remove it, discard the used bolt, and reinstall at the next point with a new COM345K-SSRB stainless bolt.
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.
- Cracks, deformation, or spreading of the swivel housing, bridge, or locking caps
- Bent, gouged, or distorted D-ring, or a D-ring that no longer swivels freely
- Damaged, stripped, or galled bolt threads, or any previously used bolt
- Pitting, crevice corrosion, or staining of the stainless surfaces
- Missing or illegible product labels and markings
- Any evidence the anchor has arrested a fall
- Cracked, spalled, or deteriorated concrete around the installation point
Remove the anchor from service immediately if it has been subjected to fall arrest forces or fails any inspection point, and destroy retired equipment so it cannot be returned to use.
