The Plate That Backs Up the Anchor
The SWX100N-QPQ-CTS is the reinforcement backer plate for the Frontline MEGA Swivel family: a 4 x 6 inch, 1/4 inch thick powder coated mild steel plate with a clearance hole for a 5/8 inch bolt. Installed on the far side of the substrate, it spreads the anchor load across the wall instead of concentrating it at the bolt hole — the difference between anchoring to a reinforced cinder block wall and pulling a cone out of it.
Rated at 10,000 lbf (44 kN) ultimate tensile strength with a 2,000 lbf working load and a 310 lb maximum user weight, the backer plate can be used with Frontline 5K and 10K MEGA Swivel anchors on reinforced cinder block walls, thick concrete walls, industrial air conditioners and chillers, metal structures, and many more. The bolt is not included — use 5/8 inch (16 mm) bolts or all thread, with the nut fully threaded to maintain the strength rating and integrity of the anchor.

Who Needs This Product
This product is a reinforcement accessory, not an anchor by itself. The MEGA Swivel anchor is the tie-off point; the wall or structure is the anchorage; the backer plate sits behind the substrate and turns a questionable bolt hole into a backed, load-spreading connection. If you are through-bolting a MEGA Swivel to block, thin concrete, or sheet-metal-clad structure, this plate belongs on the other side.
Features
Spreads the load
The 4 x 6 inch footprint distributes anchor forces across the substrate instead of concentrating them at the hole.
Built for MEGA Swivels
Designed for use with Frontline 5K and 10K MEGA Swivel anchors in through-bolt installations.
1/4 inch mild steel
A 1/4 inch thick steel plate with a 10,000 lbf ultimate tensile strength rating.
Powder coated
The powder coat finish resists corrosion on indoor and outdoor installations.
5/8 inch hardware
Clearance hole sized for 5/8 inch (16 mm) bolts or all thread, the same hardware the MEGA Swivels run.
Masonry-friendly
Makes reinforced cinder block and thick concrete walls usable anchorage substrates per the manual.

The nut must be fully threaded. The bolt is not included. Use 5/8 inch (16 mm) bolts or all thread, and thread the nut fully onto the bolt to ensure maximum strength ratings and the integrity of the anchor. Do not skip the user instructions supplied with this product — alteration or misuse may lead to serious injury or death.
Compliance Standards
Rated to 10,000 lbf UTS
The plate carries a 10,000 lbf ultimate tensile strength rating, matching the 10K MEGA Swivel anchor it backs.
2,000 lbf working load
The published working load for the backed connection per the spec sheet.
MEGA Swivel system part
Used with Frontline 5K and 10K MEGA Swivel anchors, which carry their own published compliance ratings.
Manual-governed install
Strength ratings apply only when installed with 5/8 in hardware, nut fully threaded, per the user instructions.
Typical Applications
Installation Overview
Follow the manufacturer's manual. The sequence below is an overview only.
- Verify the substrate. A competent person confirms the wall or structure can support the loads required by the MEGA Swivel manual.
- Drill through. Drill the through-hole for the 5/8 in bolt or all thread at the planned anchor location.
- Place the plate. Position the backer plate on the far side of the substrate, centered on the hole.
- Bolt the anchor. Install the MEGA Swivel with the 5/8 in hardware through anchor, substrate, and plate.
- Thread the nut fully. Tighten with the nut fully threaded on the bolt — full thread engagement is required for the rating.
- Verify before loading. Confirm the assembly is tight, the plate sits flat, and the swivel articulates freely.
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.
- Plate: bending, cracks, elongated bolt hole, or corrosion through the powder coat.
- Hardware: 5/8 in bolt or all thread undamaged, nut fully threaded and torqued.
- Substrate: cracking, crushing, or movement around the through-bolt.
- Anchor: inspect the attached MEGA Swivel per its own manual.
- Markings: product identification legible.
Retirement triggers: any fall arrest loading on the system, plate deformation, an elongated or cracked bolt hole, significant corrosion, or any condition where the inspector cannot verify the assembly is fit for service. Replace hardware rather than reusing questionable bolts.
