AMBULL D-Ring Tie Down Anchors 4-Pack — 10 Ton Carbon Steel, Rubber Isolators, Bolt-On (Black)

AMBULL D-ring tie down anchors are a four-pack of heavy-duty, bolt-on carbon steel anchors rated 10 tons each and fitted with rubber isolators for quieter, surface-saving cargo securement.

These bolt-on D-ring anchors combine high-strength carbon steel construction with a corrosion-resistant zinc and powder coat finish and include mounting hardware for straightforward installation. Each anchor pairs with a molded rubber isolator to reduce noise and protect mounting surfaces, making this set suitable for trailers, trucks, garages, and a wide range of cargo tasks. The total combined rated working load across the four anchors is 40 tons, while each ring is individually rated to a 10-ton working load limit.

How strong are these D-ring anchors and what load capacity can I expect?

Each AMBULL D-ring is rated for a 10-ton (20,000 lb) working load limit, and the set of four provides a combined rated capacity of 40 tons when all are mounted properly. The anchors are made from high-strength carbon steel to deliver the tensile strength required for heavy cargo and equipment restraint.

• Individual anchor rated: 10 tons (20,000 lbs) WLL
• Four-anchor combined rated capacity: 40 tons
• Made from carbon steel for high tensile strength
• Designed for heavy equipment, vehicles, ATVs, and large cargo

What installation steps and mounting hardware are included?

The anchors come ready to bolt on with eight bolts and lock nuts included (two bolts per ring) so you can mount them to wood or metal surfaces without welding. Standard through-bolting secures the base plate, and using the supplied lock nuts helps prevent loosening from vibration during transit.

• Includes 8 bolts and 8 lock nuts for four anchors
• No welding required; mounts to wood or metal decks
• Two-bolt base plate for stable, even load distribution
• Use recommended bolt sizes and proper torque for rated strength

How do the rubber isolators help during transport and storage?

Each D-ring comes with a custom-fit rubber isolator that cushions metal-to-metal contact, reducing rattling and vibration while protecting the mounting surface from scratches. The isolators also create a tighter, quieter fit and help extend the life of the hardware by limiting direct abrasion.

• Molded rubber pads to minimize noise and vibration
• Protects painted or finished decking from damage
• Improves fit and reduces movement under load
• Easy to replace if worn over time

Are these anchors weather-resistant and suitable for outdoor use?

The D-rings feature a zinc galvanizing base layer topped with a powder coat finish to resist corrosion and rust in outdoor conditions. This combination helps prevent deterioration from moisture and road salts, extending usable life when mounted on trailers, trucks, or outdoor storage areas.

• Zinc galvanizing undercoat for corrosion protection
• Durable powder coat top layer for weather resistance
• Suitable for marine, road, and outdoor applications
• Inspect periodically for wear and recoat if needed

Who is this for: The AMBULL 4-pack D-ring tie down anchors are aimed at anyone who needs rugged, bolt-on anchor points for heavy cargo—truck and trailer owners, RV and boat haulers, contractors moving equipment, and shop or garage users creating secure storage points. They’re also practical for fleet operators and delivery services that require dependable anchor hardware with quieter operation thanks to the included rubber isolators.
