Brophy 3/8" Bolt-On D-Ring Tie Down Anchor - 6,000 lb Rated Zinc Plated
Heavy-duty surface mount D-ring designed for secure cargo restraint. Forged steel construction with a zinc-plated finish for superior corrosion resistance and durability. Important Note: Please refer to measurement visual in the listing photos.
Overview
The Brophy LRB5 is a versatile bolt-on D-ring anchor point. Its surface-mount design allows for installation on trailer floors, truck beds, or flat-bed surfaces without needing to cut large recessed holes. Ideal for securing ATVs, equipment, and heavy loads.
R&P Service Insight
When mounting tie-downs, your anchor is only as strong as the surface it is attached to. We always recommend bolting through a structural frame member for maximum safety.
- Mounting Holes: Features 7/16" square holes designed specifically for 3/8" carriage bolts.
- Finish: Zinc plating provides excellent protection against road salt and moisture.
- Safety: 2,000 lb Working Load Limit allows for heavy-duty securement when used within rated limits.

Brand & Fitment Note
Selling Brand: Brophy
Application Reference: This listing describes a bolt-on D-ring anchor for cargo securement applications where measurements, mounting points, and installation surface are appropriate.
What This Means: This listing is for the Brophy LRB5 3/8" bolt-on D-ring tie down anchor.
Before Ordering: Verify bracket dimensions, hole spacing, bolt size, mounting surface strength, required Working Load Limit, and the number of anchors needed for the cargo being secured.
R&P Repair Insight
Tie-down hardware should be selected and installed as part of the full cargo-control system. The anchor, fasteners, backing structure, and mounting surface all work together to determine real-world securement strength.
- Surface Check: Do not rely on thin sheet metal, weak decking, or damaged trailer flooring as the only support for a heavy tie-down point.
- Fastener Check: The square bracket holes are designed for 3/8" carriage bolts; confirm bolt length, grade, backing, and nut/washer setup for your installation.
- Load Check: Choose tie-down rings according to their safe Working Load Limit and the weight of the cargo being secured.

Safety Note
Tie-down rings must be chosen according to their safe Working Load Limit. The weight of the cargo being secured must not exceed the combined WLL of the anchors being used.
For example, if you are using 4 anchors to secure a 4,000 lb load, each anchor should have a WLL of at least 1,000 lbs. This LRB5 anchor is rated at a 2,000 lb Working Load Limit when installed and used properly within the full securement system.
