AMBULL Recessed D-Ring Tie Down Anchors 4-Pack Black — 6,000 lb WLL, includes hole saw

These AMBULL recessed 1/2" D-ring tie down anchors provide four flush, noise-free anchor points rated 6,000 lbs WLL for secure, low-profile cargo retention on trailers and truck beds.

If you haul bikes, ATVs, power equipment, furniture or general freight, having durable, low-profile tie points makes loading and transit safer and neater. AMBULL's recessed D-ring kit installs into your trailer or truck floor to keep rings out of the way when not used, reduce metal rattling on rough roads, and deliver a high breaking strength backed by a reinforced 4-bolt mounting pattern. Each pack includes four anchors, hardware, and an option that bundles a 90mm hole saw drill bit so you have everything needed for installation.

How do these recessed D-rings stay flush and quiet during transit?

The AMBULL design uses a pocketed housing and an internal tension spring so each D-ring retracts fully into its cavity when released. This prevents the ring from protruding above the bed surface, creating a smooth deck for sliding cargo and reducing noise from metal movement on rough roads. The spring holds the ring snugly inside the cup, which also lowers the chance of accidental snagging.

• Spring-loaded retraction keeps rings flush when not in use
• Low-profile housing prevents cargo hang-ups and snags
• Reduced metal-on-metal rattling during transport

What strength and mounting features ensure these anchors hold heavy loads?

Each D-ring anchor is tested to a 6,000 lbs Working Load Limit and a 12,000 lbs maximum breaking strength, providing a substantial safety margin for strapped cargo. The unit fastens with a reinforced backing plate and a four-bolt pattern for improved load distribution and structural integrity compared with single- or double-bolt styles. This setup minimizes movement and helps the fastener resist pull-through under high tension.

• 6,000 lbs WLL per anchor, 12,000 lbs break strength
• Reinforced backing plate for even load distribution
• Secure 4-bolt mounting reduces stress on mounting surface

How does the finish and construction perform in outdoor conditions?

AMBULL forges each anchor from high-strength carbon steel and applies a two-stage protective finish: an electro-galvanized middle layer for corrosion resistance, then a powder coat for surface durability. This dual-layer defense resists weathering, salt, and road grime while remaining easy to clean. The black finish also provides a discreet, professional appearance that complements most trailer and truck beds.

• Forged carbon steel core for structural toughness
• Electro-galvanized layer plus powder coat for corrosion resistance
• Black finish hides wear and matches vehicle beds

What comes in the kit and what should I prepare for installation?

The package includes four AMBULL 1/2" recessed D-ring anchors and mounting hardware; select kits add a 90mm hole saw drill bit so you can cut the mounting pockets. Before you buy, verify your trailer floor thickness and that you can access the underside for bolting and backing plate placement. Proper preparation—measuring, clearing wiring, and confirming backing plate orientation—will make installation straightforward and secure.

• Four recessed D-ring anchors and necessary screws included
• Optional 90mm hole saw bundle available for clean pocket cuts
• Confirm floor depth and underside access prior to drilling

Who this is for: The AMBULL recessed D-ring kit is ideal for owners of enclosed trailers, utility trailers, truck beds or cargo vans who want durable, low-profile anchor points to secure motorcycles, ATVs, tools, boxes and heavy equipment. It's well suited to professional haulers, contractors, outdoor enthusiasts, and anyone who values cleaner deck space, quieter transit, and high-strength tie-down points. If you need heavy-duty anchors that stay out of the way when not in use and offer clear installation guidance, this kit is a practical choice.
