Airline rails in comparison - which lashing rail is right for your van or camper?

Airline rails have established themselves as the standard for professional load securing in vans, trailers, motorhomes and service vehicles. However, different profiles are more or less suitable depending on the vehicle, area of application and desired installation method. On this page, we compare the most important semi-circular airline rail variants: Heavy-duty rails for securing wheelchairs, standard profiles for heavy loads, lightweight profiles for camper conversions and particularly slimline slim profiles for tight installation situations.

What is an airline rail and how does it work?

An airline rail is an aluminum profile with special round holes or recesses into which so-called airline fittings are clipped. These fittings can be used to securely connect lashing straps, locking beams, wheelchair securing systems or modular furniture and fittings to the vehicle structure. The rail is firmly bolted or glued to the body, floor, wall or furniture and thus forms a resilient basis for flexible lashing points.

Structure and mode of operation

The fittings are hooked into the round holes of the airline rail and lock securely into the profile. The connection remains stable under load, while the position of the fittings along the rail can be adjusted at any time. This allows loads, trolleys, furniture modules or leisure equipment to be securely fastened and quickly reconfigured if necessary.

Advantages of airline rails in the vehicle

• Flexible positioning of the lashing points along the rail
• high load capacity with low dead weight (aluminum)
• Professional, standard-compliant load securing possible
• clean integration into floors, side walls, ceilings and furniture
• ideal for vans, campers, motorhomes, trailers and workshop vehicles

Airline rail profiles at a glance

Airline rails differ primarily in terms of profile shape, material thickness, width and fastening method. In practice, semi-circular profiles have proven themselves in different variants: Heavy-duty rails for securing wheelchairs, standard profiles for general load securing as well as special light and slim versions for camper and interior fittings.

Heavy-duty airline rail for securing wheelchairs and power knots

The heavy-duty airline rail in a half-round profile is made of particularly high-strength aluminum and is tested according to DIN 75078-2 for securing wheelchairs. In combination with wheelchair restraint systems, power nodes and tested fittings, it provides a stable basis for safe wheelchair transportation. At the same time, it is also suitable for securing heavy goods such as machines, motorized wheels or power units.

Fastening is carried out according to clearly defined specifications, for example with M6 screws of strength class 10.9, a narrow screw connection grid and counter plates or rivet nuts. You can find more information in the heavy-duty airline channels category.

Standard airline rail half-round profile – drilled

The standard airline rail with drilled pattern is the right choice if you are looking for a lashing rail that is quick to install. It is usually pre-drilled in a 10 cm grid for M5 or M6 countersunk screws and can be mounted directly on the vehicle floor, side wall or in the rear garage. This creates a professional lashing system for toolboxes, crates, pallets or bulky goods without additional drilling work in the rail.

This variant is particularly suitable for courier vehicles, tradesmen's vans and trailers. You can find suitable models in the category Standard airline rails, semi-circular drilled.

Standard airline rail, half-round profile – undrilled

Drilled standard airline channels in a half-round profile are aimed at users who want to set their fixing points completely individually. The holes can be precisely adapted to reinforcement plates, frame profiles or furniture constructions. Alternatively, full-surface bonding with construction adhesive, such as Sikaflex 554 black or Sikaflex 554 weiß, possible.

This variant is particularly popular in motorhome and camper conversions, but also in rear garages or on modular extensions. You can find a large selection at Airline rails semi-circular undrilled.

Airline rail half-round profile Light – light and ideal for campers

The Light semi-circular airline rail combines low weight with high stability, making it one of the most popular solutions for the conversion of campers, motorhomes and light vans. Made from high-quality aluminum, the Light rail is suitable for both commercial vehicles and private conversion projects where any additional load counts.

It can be screwed or glued in place and is compatible with common airline accessories such as fittings, lashing straps, locking bars and end caps. Typical applications include securing camping furniture, bicycles, boxes and outdoor equipment. The Light profiles are available in lengths from 0.5 m to 3 m – further information can be found in the category Airline rail semi-circular profile Light.

Airline rail semi-circular Slim – the space-saving 40 mm profile

The airline rail Slim in half-round design is only 40 mm wide, making it the right choice when space is at a premium. The slim profile fits perfectly in narrow side walls, on roof racks, in rear garages or in narrow spaces in the vehicle. Thanks to the pre-drilled M5 countersunk holes in a 100 mm grid, installation is particularly quick.

If additional stability is required, further holes can be drilled in a narrower grid or the rail can also be glued with a construction adhesive. In combination with tensioning straps, locking rods and airline fittings, this creates a very versatile securing system. Find out more at Airline rail half-round slim.

Accessories for airline rails

Only with the right accessories can airline rails develop their full strength. Selected examples:

• Airline fittings & end fittings: Single-Stud, Double-Stud, Quattro-Stud and other fittings for holding lashing straps and eyelets.
• Lashing straps with airline end fittings: available in various lengths, ideal for quickly securing boxes, tools, luggage or motorcycles.
• Locking bars & locking beams: form-fitting securing, depending on the model with high locking force in the direction of travel.
• End caps: for a clean, secure finish without sharp edges.
• Construction adhesives: such as Sikaflex 554 black or Sikaflex 554 white for bonded assemblies without additional drilling.

Practical tips for the installation of airline rails

Check the substrate and load

Before every installation, the load-bearing capacity of the surface should be checked. The vehicle floor, cross-members, sidewalls or panel constructions must be able to reliably absorb the forces that occur. Particularly for heavy-duty and safety-relevant applications, attention should be paid to solid counter plates, rivet nuts and sufficient material strength.

Pay attention to installation distances and screw quality

Screw spacing, screw quality and substructure are crucial for bolted systems. For heavy-duty rails in particular, M6 screws with a high strength class (e.g. 10.9) and a narrow screw spacing are often used. The manufacturer's installation guidelines should always be observed.

When bonding airline rails, adhesive surfaces must be clean, grease-free and strong. Depending on the material (metal, wood, GRP, sandwich panels), suitable primers and pre-treatments are required. The manufacturer's instructions on curing times, processing temperatures and layer thicknesses should be followed exactly to ensure a permanently resilient bond.
