MEGA Swivel 10K Concrete Anchor
The Frontline COM3410K is the 10,000 lbf member of the MEGA Swivel anchor family. Its swivel ring design lets the D-ring rotate a full 360 degrees and flip back and forth by 180 degrees, so your lifeline stays aligned with the worker instead of side-loading the connector. The strength comes from heavy-gauge heat-treated alloy steel, a reinforced bridge, and locking caps, 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, work the area, then remove it and relocate with a new COM3410KRB replacement bolt. Rated at 10,000 lbf ultimate tensile strength with a 2,000 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 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 10,000 lbf ultimate tensile rating.
Reusable anchor body
Remove the anchor and relocate it across the job. Each new anchoring point requires a replacement bolt for COM3410KRB.
Zinc plated finish
Zinc plating on the steel swivel assembly resists jobsite corrosion through repeated installs.
Multi-orientation installation
Works on vertical, horizontal, and overhead concrete surfaces: 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 COM3410KRB 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 COM3410K bolt.
- Clean. Blow out and brush the hole to prevent dust and debris from compromising 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 COM3410KRB 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 has failed any inspection point, and destroy retired equipment so it cannot be returned to use.
