AMBULL D-Ring Tie Down Anchors 4-Pack — Black Bolt-On, 10 Ton Each, Rubber Isolators

AMBULL D-ring tie down anchors are heavy-duty bolt-on anchors with rubber isolators that secure up to 10 tons each for transporting equipment and cargo safely.

These bolt-on D-ring anchors are built from carbon steel, finished with zinc plating and a protective powder coat, and shipped as a 4-pack with mounting hardware and rubber isolators. They’re intended for permanently mounting to trailers, trucks, garages, or wooden decks to provide solid attachment points for straps, chains, and ropes. The isolators reduce noise and protect surfaces while the included bolts and lock nuts make installation straightforward on both metal and wood substrates.

How strong are these anchors and what load can I expect?

Each D-ring is rated for a 10-ton working load limit (20,000 lbs). When all four anchors are installed, the combined working capacity totals 40 tons, assuming proper mounting to a structure capable of supporting those forces. Ratings apply to the hardware and anchor design; the mounting surface and fasteners must also be rated accordingly.

• Single anchor working load: 10 tons (20,000 lbs)
• Pack total working load: 40 tons across 4 anchors
• Made from high-strength carbon steel for structural integrity
• Use appropriate rated bolts and reinforcement for full load capacity

What does the rubber isolator do and why is it included?

The custom-fit rubber isolators sit between the D-ring and the mounting surface to damp vibration and minimize metal-on-metal contact. This reduces rattling and helps protect painted surfaces from scratches, prolonging both the anchor finish and the vehicle or trailer surface. They also help reduce wear on the anchor pivot over repeated use.

• Noise reduction during transit and operation
• Surface protection from scratches and abrasion
• Vibration damping to extend hardware life
• Easy to position and install with the anchor plate

How do I install these D-ring anchors and what hardware is provided?

Installation is bolt-on and requires no welding. Each anchor in the 4-pack ships with two bolts and lock nuts (eight bolts total) sized to secure the anchor through the mounting surface. They can be fitted to metal or wood surfaces; for heavy loads, reinforcing the mounting area or using backing plates is recommended.

• Comes with 8 bolts and lock nuts for the 4 anchors (2 bolts per anchor)
• Bolt-on design—no welding required
• Suitable for wood or metal mounting surfaces
• Consider backing plates or frame reinforcement for maximum load transfer

Where can I use these anchors and what vehicles or projects suit them?

These anchors are versatile for transport and storage applications. Typical uses include securing heavy equipment, motorcycles, ATVs, boats, and cargo in trailers, pickup beds, RVs, delivery boxes, or garage floors. They’re also useful in workshop and warehouse setups for anchoring machinery or shelving.

• Trailers, pickup trucks, and flatbeds
• Motorcycle/ATV transport and tie-down points
• RV cargo compartments, boat trailers, and delivery boxes
• Garages, warehouses, and equipment storage mounts

Who is this for? The AMBULL D-ring 4-pack is aimed at vehicle owners, fleet operators, cargo haulers, and DIY mechanics who need rugged, permanent tie-down points with reduced noise and surface protection. Choose these anchors if you want bolt-on, corrosion-resistant hardware with strong working load ratings and included mounting fasteners for straightforward installation. Remember to verify your vehicle or mounting surface strength and use proper reinforcement to achieve the rated capacities.
