Lonffery Recessed D-Ring Tie Down Anchors 4-Pack — 6,000 lb Zinc-Coated Heavy-Duty Flush Mount Kit with Backing Plates

Lonffery recessed D-ring tie down anchors are a four-piece heavy-duty kit designed to add low-profile, 6,000 lb-rated tie points to trailers, trucks, and cargo spaces.

These recessed D-ring assemblies provide strong, corrosion-resistant anchor points that sit flush when not in use and flip up into a secure ring when you need to strap down loads. The kit includes backing plates, recessed rings, carriage bolts, and self-locking nuts so you can add reliable tie-downs to wood or metal decks, trailers, and vehicle beds with basic tools.

How much weight can each D-ring handle and what does the 6,000 lb rating mean?

Each recessed D-ring in this Lonffery kit is manufactured and rated to a 6,000 lb assembly break strength. That rating describes the maximum load the assembly is designed to withstand before failure under ideal conditions.

• 6,000 lb break strength per D-ring under standard testing conditions
• Zinc-coated steel construction to resist corrosion and preserve strength
• Includes full hardware to assemble and distribute load across the backing plate

What parts come in the 4-pack and how do they fit together?

The kit is a complete set: four recessed D-rings, four backing plates sized to spread load, 16 carriage bolts and 16 self-locking nuts to secure them. The backing plate nests under the deck surface while the recessed cup and ring sit flush when stowed.

• Backing plates: 4-7/8" x 4-1/2" to distribute forces over the deck
• Recessed D-rings: 3" x 3-1/4" opening, folds flat when not in use
• Hardware: 16 carriage bolts and 16 self-locking nuts for a secure attachment

How easy is installation and what tools are required?

Installation is straightforward and designed for common DIY skills: a hole saw creates the recessed pocket and a chisel or file cleans up the opening. Most people can bolt the assemblies in place in minutes per anchor when the mounting surface and bolt patterns are prepared.

• Required tools: hole saw sized to the recessed cup, drill, wrench or socket for bolts
• Surface prep: route or chisel a flush pocket for the backing plate and cup to sit level
• Fastening: use provided carriage bolts and self-locking nuts; torque to recommended tension

What applications are these D-rings best suited for?

Lonffery recessed D-rings work well anywhere compact, heavy-duty tie points are needed. They are commonly installed in trailers, pickup beds, cargo vans, flatbeds, utility trucks, and boat decks to secure machinery, motorcycles, pallets, or tied-down freight.

• Trailer and truck beds: secure furniture, equipment, or heavy appliances
• Towing and transport: immobilize motorcycles, ATVs, or vehicle parts
• Commercial use: pallet and crate restraint for deliveries and logistics
• Marine docks and decks: anchor lines where corrosion resistance is required

Who is this for: This Lonffery 4-pack is aimed at fleet operators, contractors, weekend warriors, and anyone who needs reliable, low-profile tie-downs that can handle heavy loads. If you maintain trailers, retrofit vehicles for cargo control, or want to add professional-grade anchor points without bulky hardware, this kit offers a durable, corrosion-resistant solution with all necessary components for installation.
