The Anti-Rack Ring is a vital steel component used in the door locking system of ISO shipping containers. Its purpose is to prevent deformation of the container door frame caused by twisting forces during transport, handling, or stacking. By acting as a mechanical stop on the locking rod, the ring helps maintain proper alignment of the door and ensures smooth operation of the locking mechanism.

Manufactured from high-strength structural steel and typically hot-dip galvanised for corrosion resistance, the anti-rack ring is designed for long-term durability in harsh transport environments, including maritime conditions.

Each standard container uses eight anti-rack rings, positioned next to the locking rod brackets on the container doors. These rings help maintain structural stability, ensure a proper door seal, and support safe cargo transport.

Key Specifications

• Material: SS400 / Q235B structural steel

• Surface Finish: Hot-dip galvanised or cold galvanised

• Inner Diameter: 11 mm (7/16″)

• Outer Diameter: 28–32 mm

• Thickness: 7–10 mm

• Weight: approx. 0.05–0.06 kg

• Compatibility: Standard 20 ft and 40 ft ISO shipping containers

The anti-rack ring is an essential spare part for container maintenance and repair, helping ensure containers remain safe, secure, and fully functional throughout their service life.

High Strength Bush & Rivet Assembly for Container Door Mechanisms

Product Overview

The Rivet For Handle Hub is a critical component of the container door locking system. It consists of a precision bush and high strength rivet assembly designed to ensure smooth rotation, secure fastening, and long term durability of the door handle mechanism.

Engineered for demanding marine and intermodal environments, this assembly plays a key role in maintaining safe, reliable container door operation.

Product Definition

The Bush & Rivet assembly includes two integrated components:

Bush

Acts as a sliding bearing within the rotating joints of the door handle and locking rod mechanism.

Rivet

A permanent fastening element that securely holds the bush and associated components in place.

Location in the Container

Installed within the rotating joints of the door handle system, specifically where:

• The handle operates the locking rod

• Force is transmitted to the top and bottom locking cams

This is a high movement, high stress area requiring precision and durability.

Function & Performance

Why Proper Bush & Rivet Function is Critical

• Prevents door jamming and operational failure

• Reduces vibration and operational noise

• Protects handle and locking rods from premature wear

• Minimizes play that could compromise sealing and cargo security

• Extends overall lifespan of the door locking assembly

Materials & Construction

• High strength steel construction

• Cast steel bushings for durability and wear resistance

• Cold formed steel rivets for optimal strength and ductility

Designed to withstand heavy operational loads and harsh environmental conditions.

Installation & Replacement

Standard Repair Procedure

1. Drill out and remove the old rivet

2. Extract the worn bush

3. Insert the new bush

4. Install new rivet using rivet gun or professional tool

   • Blind rivets require no rear access

5. Perform functional check for smooth movement and correct alignment

Maintenance & Inspection

Recommended Inspection Frequency

• During major container repairs (doors, locking rods, flooring)

• Typically every 2–5 years, depending on usage intensity and environmental exposure

Common Replacement Causes

• Bush wear (handle wobble)

• Corrosion damage

• Damage from improper door system intervention

Key Benefits

Smooth and reliable door operation
Long service life
