MEGA Swivel 5K Concrete Anchor
The Frontline COM345K brings the MEGA Swivel design to the standard 5,000 lbf anchor class. Its swivel ring lets the D-ring rotate a full 360 degrees and flip back and forth 180 degrees, keeping the lifeline aligned with the worker instead of twisting or side loading the connector. Heavy gauge heat treated alloy steel, a reinforced bridge, and locking caps carry the load, while the patent pending key lock design keeps the D-ring seated in its swivel housing and prevents the steel from spreading under heavy loads.
The anchor body is reusable: install it in sound structural concrete with the included 0.75 in concrete bolt, work the area, then remove and relocate it with a new COM345KRB 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 plus OSHA CFR 1926.502 and 1910.140.
Who Needs This Product
This product is a reusable concrete anchorage connector. It provides the anchor-side tie-off point of a personal fall arrest or fall restraint system on concrete walls, ceilings, columns, and decks. 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
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 across the work area.
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.
Heat treated alloy steel
Heavy gauge heat treated alloy steel with a reinforced bridge, D-ring, and locking caps delivers the 5,000 lbf tensile rating.
Reusable anchor body
Remove the anchor and relocate it across the job. Each new anchoring point requires a fresh COM345KRB replacement bolt.
Compact and light
At 5 in tall and under a pound, it disappears into a gear bag and installs through a 0.75 in concrete bolt.
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 MEGA Swivel anchor body is reusable, but the concrete bolt must be replaced with a new COM345KRB bolt every time the anchor is moved to a new anchoring point. Never reinstall a used bolt, and only install the anchor 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 0.75 in COM345K 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 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 COM345KRB 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 corroded bolt threads, or any previously used bolt
- Corrosion or significant loss of the zinc plated finish
- 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.
