Bolt-On D-Rings for Shipping Container Shelving Brackets or Extra Lashing Points

In this video, we will show you how to install shelving on the end walls and sidewalls of your shipping container using the Bolt-On D-Ring and Shelving Brackets.

This is a quick and easy way to install shelves in your sea can without welding or puncturing holes through the container walls. You can use this product to help organize your shipping container shed, storage unit, office, or home.

This product also allows you to add lashing points to secure freight and container stuffing while also keeping it wind and watertight and cargo-worthy. The D-Rings are laser-cut so you can install them on the floor or ceiling of end walls or sidewalls of a Conex box.

Bolt-On D-Rings for Shipping Containers: A No-Weld Shelving Solution

In this walkthrough, Channing McCorriston, The Container Guy, introduces a bolt-on d-ring system designed to make interior shelving installation easier and cleaner inside 20-foot, 40-foot, and 53-foot shipping containers.

This solution addresses one of the biggest limitations with traditional container fittings: the need for welding, especially on end walls where d-rings were previously difficult or impossible to install without damaging the container.

The Problem with Traditional D-Rings

Standard d-ring installations typically require welding.

While welding creates a strong connection, it also burns off the factory paint. Over time, this leads to rust and corrosion. For customers who want to maintain the structural integrity and longevity of their container, avoiding paint damage is critical.

Additionally, certain areas of the container, particularly end walls on 20-foot and 40-foot units, are not easily compatible with conventional welded d-rings.

The Bolt-On D-Ring Solution

The bolt-on d-ring eliminates the need for welding entirely.

Key advantages include:

• Installation anywhere along sidewalls of 20-foot and 40-foot containers

• Compatibility inside 53-foot containers

• Special profile shape designed to fit end wall corrugations

• No paint damage

• No long-term rust issues caused by burned coatings

• Installation into hollow 2x2 tubing inside the container walls without penetrating through the container exterior

Because the system bolts directly into internal structural members, it maintains container integrity while providing strong anchor points.

Tools Required for Installation

Installation is straightforward and requires only basic tools:

• Drill with 9/32-inch drill bit

• Impact driver or drill with half-inch socket or impact bit

• Marker for hole placement

• Center punch to prevent drill bit wandering

• Safety glasses

No specialized fabrication tools or welding equipment are needed.

Step-by-Step Installation Overview

1. Mark the Holes

Hold the d-ring in the desired position and mark the two mounting holes.

If necessary, trim away excess caulking so the d-ring sits flush against the corrugated surface.

2. Center Punch

Use a center punch on each marked location. This prevents the drill bit from walking across the metal surface.

3. Drill the Holes

Drill both holes using a 9/32-inch drill bit.

4. Mount the D-Ring

Attach the d-ring using self-threading bolts into the internal 2x2 tubing. Tighten securely using an impact driver or socket.

Once installed, the d-ring is ready to support shelving brackets.

Shelving Compatibility

The bolt-on d-ring system is specifically designed to support container shelving setups.

Here’s how it works:

• Shelving brackets hang from d-rings mounted near the ceiling.

• A bottom t-bar slots into a lower d-ring to keep shelving plumb and properly aligned.

• Lumber attaches directly to the shelving brackets using nails, eliminating the need for additional fasteners.

• Two bolts per bracket secure the shelving system firmly in place.

This creates a strong, stable shelving structure without complicated hardware or permanent modifications.

Why This System Matters

This bolt-on d-ring solution solves several long-standing challenges:

• Enables shelving on container end walls

• Prevents rust caused by welding

• Preserves factory paint and coatings

• Simplifies installation

• Reduces modification costs

• Improves long-term durability

For individuals and businesses looking to maximize storage efficiency inside containers, this system provides flexibility without compromising the container itself.

Final Thoughts

The bolt-on d-ring is a practical upgrade for anyone modifying shipping containers for storage, workshop use, or industrial applications.

By eliminating welding, protecting factory coatings, and allowing secure shelving installation in previously inaccessible areas, this system significantly improves container usability while maintaining structural integrity.
