The Airholder system consists of the following profiles: S-profile, B-profile and A-profile.

Airholder is a modular roof rack system that is not made up of many arbitrary individual parts, but rather built on a clear technical foundation. At its core are three proprietary Airholder aluminum profiles (S, B, and A), which can be combined depending on the vehicle and intended use. This logic ensures high rigidity, clean mounting points, and flexible configurations – from transporting luggage to expedition setups with a rooftop tent, awning, and auxiliary lights.

Profile Overview: S, B, and A in Comparison

1) S-Profile – the side profile that defines the geometry

The S-profile is the central side, load-bearing profile. It forms the left and right sides of the structure and defines the basic geometry of the roof rack: contour, position on the roof, and the alignment of components along the vehicle's length.

100-mm grid drilling and marking for individual adjustment

To ensure the system remains truly modular in practice, we have provided two levels of flexibility in the S-profile:

• Standard drillings in a 100-mm grid – a clear "grid" that allows components to be positioned quickly, cleanly, and reproducibly.

• A defined marking (score/index line) for additional drillings – if a position outside the grid is needed, the customer can drill along this marking and place components exactly where it makes sense for their application.

This allows for maximum freedom in adapting to the intended use – e.g., awning, auxiliary lights, special brackets, load securing, or a rooftop tent setup.

2) B-Profile – the rigid structural profile with internal T-slot

The B-profile is the structural, rigid profile in the system. It is designed to safely support loads and integrate fastenings cleanly.

Important: The B-profile features an internal T-slot receiver. This offers clear advantages:

• Fastenings and modules can be mounted stably and cleanly.

• Components can be shifted lengthwise and precisely aligned.

• The system remains expandable: retrofitting and reconfiguring is significantly easier than with solutions that rely purely on fixed drilling points.

In addition, the B-profiles are already designed to be very rigid, so that no plastic deformations (i.e., no "indentation" in the contact area) should occur under localized loads.

3) A-Profile – our unique profile with an airline track and internal T-slot

The A-profile is a unique Airholder profile that combines two mounting "interfaces":

• Airline track as a universal interface for lashing points, fittings, and adapters,

• Internal T-slot receiver for additional fastenings, modules, and individual solutions.

Heavy-Duty Airline Version

The airline track in the A-profile is designed as a reinforced heavy-duty version:
We have deliberately increased the wall thicknesses and the webs/flanges of the track to achieve additional rigidity precisely in the area of the airline interface – where concentrated forces from straps, lashing points, or individual fixing points often occur.

4) Front and Rear Sections: two possible profile combinations

With Airholder, the front and rear sections are not limited to a single rigid design. Depending on the vehicle and application, the profiles can be combined in two variants at the front and rear:

• S + B – if the focus is on structural rigidity and T-slot mounting logic.

• S + A – if the airline function (Heavy Duty) and flexible mounting options are paramount.

This allows the "edges" of the rack to be specifically adapted to real-world use: sometimes maximum structure is important, sometimes maximum lashing and mounting flexibility.

5) Overall Roof Rack Configuration: S + A, S + B, or S + A + B

The great advantage of the modular Airholder system: The roof rack is configured for the task – not the other way around. Therefore, the entire system can be built in different ways:

Variant 1: S + B

Focus on rigidity and structural foundation. Ideal when a stable basic structure and a cleanly integrated mounting principle via T-slot are paramount.

Variant 2: S + A

Focus on universal lashing and mounting points via the airline track (Heavy Duty) plus additional flexibility via the T-slot.

Variant 3: S + A + B

Combination of both approaches – when different requirements exist depending on the area: structural rigidity in one place, maximum mounting and lashing flexibility in another.
