4-Pack Brophy LRB5 3/8" Bolt-On D-Ring Tie Down Anchors 6,000 lb Zinc
Four heavy-duty surface mount D-ring anchors designed for building a complete cargo restraint setup. Forged steel construction with zinc-plated finish for strength, corrosion resistance, and dependable trailer or truck-bed tie-down performance. Important Note: Please refer to measurement visual in the listing photos.
Overview
This LOT OF 4 Brophy LRB5 set gives you four matching bolt-on D-ring anchor points for trailer floors, truck beds, flat-bed surfaces, utility trailers, equipment trailers, and other properly reinforced cargo-control mounting locations. A 4-pack is ideal when creating a full tie-down pattern around a load, adding corner anchor points, or outfitting a trailer deck with multiple securement locations.
R&P Service Insight
When mounting tie-downs, your anchor system is only as strong as the surface it is attached to. We always recommend bolting through structural members or properly reinforced backing plates whenever possible.
- Mounting Holes: Each anchor features 7/16" square holes designed specifically for 3/8" carriage bolts.
- Finish: Zinc plating provides strong protection against moisture, road grime, and regular trailer use.
- Safety: Each anchor has a 2,000 lb Working Load Limit when installed and used properly within rated limits.

Installation Notes: Please refer to the measurement visual in the listing photos. Verify bracket size, bolt hole spacing, bolt size, mounting surface strength, and anchor placement before installation.
Performance Insight: Each forged 3/8" steel ring and zinc-plated bracket provides strength, durability, and corrosion resistance for regular trailer and cargo-control use.
Brand & Fitment Note
Selling Brand: Brophy
Application Reference: This listing describes a 4-pack of bolt-on D-ring anchors for cargo securement applications where measurements, mounting points, and installation surfaces are appropriate.
What This Means: This listing is for four Brophy LRB5 3/8" bolt-on D-ring tie down anchors.
Before Ordering: Verify bracket dimensions, hole spacing, bolt size, mounting surface strength, required Working Load Limit, cargo weight, tie-down angle, 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 anchors, fasteners, backing structure, straps, 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 heavy tie-down points.
- 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, and anchor placement, tie-down angle, strap rating, fasteners, and mounting structure all matter.
Each LRB5 anchor in this 4-pack is rated at a 2,000 lb Working Load Limit when installed and used properly within the full securement system. Using four anchors may provide up to 8,000 lbs combined WLL only when all anchors, mounting surfaces, fasteners, straps, and load angles are properly rated and configured.
