LoadMax®: Internal Roof Rack Support System

For Australian trade and fleet operators, roof load management isn’t just about convenience—it’s a critical safety and performance consideration. Whether you’re transporting ladders, building materials or oversized equipment, roof rack systems must be properly supported to protect your vehicle, your gear and your livelihood.

Enter Milford’s LoadMax® Universal Roof Rack Support System—engineered to provide maximum load stability and prevent costly canopy damage in work-ready utes fitted with canopies or caps.

Built to Handle the Load, Engineered to Prevent the Damage

Unlike external rack setups that can stress canopy structures, LoadMax® works from the inside. This internal support system is designed to distribute roof rack loads directly to the ute body, dramatically reducing stress points on the canopy or cap. The result? Increased roof carrying capacity, reduced risk of fatigue damage, and long-term confidence on the job.

Tested and rated to AS/NZS 1235 and ISO 11154, LoadMax® is trusted to deliver performance under real working conditions.

Key Components and Features

Each LoadMax® kit includes:

• Four Heavy-Duty Uprights
  Constructed from 38mm tubular steel, these uprights feature multiple bend radii for a form-fitting installation that maximises available cargo space without compromising strength. The powder-coated finish and capped ends ensure durability in harsh worksite conditions.
• Sure-Grip Clamps with Precision Bed Rail Attachments
  These mounts provide fully adjustable rotational movement, enabling compatibility with most ute tubs and cap styles. The clamps also apply additional sealing pressure between the canopy and tub rail, helping reduce water and dust ingress.
• Unique Roof Rack Couplings
  Designed to fit both single and dual skin canopies, these adjustable couplings provide direct structural support under each roof rack mounting point. Their alignment helps eliminate thermocycling cracks, a common issue in unsupported canopy installations.
• Designed for Universality and DIY Fitment
  The LoadMax® system has been designed for broad compatibility across a wide range of vehicle tubs and canopy combinations. While installation may require functional trade-offs in some configurations, the system offers a strong, universal solution for most applications—including both single and dual cab utes.

Critical Notes for Fitment and Use

While LoadMax® has been engineered to suit a wide range of utility vehicles, it is not compatible with J-deck style tubs, and may not suit all canopy styles or brands. Always check detailed product dimensions before purchase to ensure compatibility with your specific vehicle, cap and roof rack combination.

Importantly, while LoadMax® is tested to exceed the strength of most vehicle tubs, you must never exceed your vehicle’s manufacturer-stated roof or tub load limits—whether static or dynamic.

Installation Notes

Due to the universal design of the LoadMax® internal roof rack support system against the myriad of vehicle body tubs/trays and the wide array of canopy & cap combinations available, a compromise of some tub/tray or canopy/cap function may be required to achieve proper fitment. It is essential that you familiarise yourself with the detailed, dimensioned product images below in order to determine product suitability for your vehicle & canopy/cap and roof rack combination. Please ensure that the sizes & dimensions of the LoadMax® suit your specific application PRIOR TO PURCHASE. Milford cannot provide refunds for sizing or vehicle, canopy, cap or roof rack incompatibility issues.

We always recommend locating the Roof Rack Couplings to the horizontal area of the canopy/cap roofline (never on the corner radii). In instances where the Sure Grip Clamps mounting possibility is constrained, the Heavy Duty Uprights may cover some of the canopy/cap side window area. The tested capacity of the LoadMax® substantially exceeds the maximum capability of the body tub and the safe operating limits of your vehicle. Contact your vehicle manufacturer for the maximum body tub load. We recommend that you never exceed either the maximum tub load or the safe operating roof load; statically or dynamically and as identified by the vehicle and the canopy/cap manufacturer.
