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

These AMBULL D-ring tie down anchors are a 4-pack of bolt-on carbon steel anchors rated to a combined 40-ton capacity, each fitted with rubber isolators to reduce noise and protect surfaces during heavy-duty cargo securement.

Built for demanding transport and storage tasks, the AMBULL D-ring anchors blend heavy-duty strength with weather resistance and vibration-damping features. Each anchor is zinc-galvanized and powder-coated for corrosion protection, ships with the bolts and lock nuts needed for installation, and includes molded rubber isolators to cushion metal-to-metal contact. They’re intended for trucks, trailers, garages, and industrial or recreational gear restraint where secure tie points matter.

How much weight can each AMBULL D-ring hold and what does that mean in practice?

Each individual D-ring is rated for a 10-ton (20,000 lb) working load limit, and the set of four provides a cumulative rated capacity of 40 tons when used across multiple secure points. Ratings assume correct installation to a suitable structural surface and distribution of load across anchors rather than placing the entire load on a single ring.

• Individual ring rating: 10 tons (20,000 lbs) WLL
• Four-ring combined rated strength: 40 tons total
• Best practice: attach loads across multiple anchors to match rated capacities

What makes these anchors quieter and less damaging to surfaces?

Each AMBULL D-ring ships with a custom-fit rubber isolator that sits between the D-ring and the mounting surface. The isolator cuts down on metal-on-metal clanking and absorbs vibration, which reduces noise, helps prevent scratches, and extends the life of both the anchor and the mounting area.

• Rubber isolators minimize transit noise and vibration
• Isolators protect painted or finished surfaces from abrasion
• Removable design allows maintenance or replacement if worn

How durable are these anchors outdoors and how do I install them?

AMBULL D-rings combine a zinc galvanizing base layer with a powder coat finish for reliable corrosion resistance in outdoor environments. Installation is straightforward: each anchor mounts with two supplied bolts and lock nuts, suitable for wood or metal substrates without the need for welding.

• Finish: zinc galvanize plus powder coat for rust resistance
• Installation: bolt-on with included 8 bolts and lock nuts (2 bolts per ring)
• Compatible mounting surfaces: wood decking, trailer frames, truck beds, or reinforced metal plates

Where can I use these D-rings and what are practical applications?

These tie down anchors are versatile for transport and stationary storage tasks. Use them to secure motorcycles, ATVs, generators, furniture, boats, kayaks, or palletized equipment; they’re also useful in garages, warehouse racking, and delivery boxes for stable tie points.

• Vehicle applications: trailers, pickup beds, RVs
• Recreational gear: ATVs, motorcycles, kayaks, boats
• Storage and industrial: garage floors, shelves, delivery containers

Who is this product for? Professional haulers, fleet managers, tradespeople, and homeowners who need high-strength, corrosion-resistant anchor points will benefit from the AMBULL D-ring set. If you move heavy equipment or value quieter, surface-safe tie points on trailers and trucks, this bolt-on 4-pack offers a rugged, ready-to-install solution with the mounting hardware and isolators included.
