NAFTA chassis clamps/frog clamps for H- and I-beam structures
NAFTA chassis clamps, also known as beam clamps, are used for the fast and secure mounting of components on H- and I-beam structures without the need for drilling. Consequently, these clamps are widely used in trailer construction, bodywork, industrial structures, and various custom projects. Due to their flat shape and broad pressure distribution, the heavy-duty versions are particularly popular for professional applications.
A significant advantage is that the clamps can be easily slid along the main beam. This creates extra flexibility when mounting and relocating accessories or superstructures. Furthermore, components can be quickly repositioned when the configuration changes. In this way, the construction remains efficient, organized, and easily adaptable.
NAFTA chassis clamps/frog clamps applications
In practice, these clamps are applied for a wide range of accessories and structural components, such as:
- fire extinguishers
- toolboxes
- water tanks
- air pressure vessels
- pallet boxes
- spare wheel carriers
- side protection
- wheel arches and fenders
- panels, cooling boxes, and similar accessories
Depending on the chosen version, NAFTA chassis clamps are suitable for both light accessories and heavy structures. Moreover, the clamps can be easily moved and readjusted. This makes the system particularly practical for changing superstructure configurations. At the same time, the assembly remains flexible and efficient in daily use.
NAFTA adjustable and heavy-duty applications
For lighter accessories and standard mounting, adjustable NAFTA clamps offer a practical solution. When larger structures need to be attached, such as cooling boxes, panels, or similar accessories, the heavy-duty flat versions are better suited. Thanks to the broad pressure distribution, these beam clamps also function excellently on wood, plastic, and sandwich panels.
The heavy-duty NAFTA chassis clamps also provide extra stability during intensive use. As a result, structures remain firmly and safely attached, even under high loads. Because these versions were developed for long-term loading in demanding conditions, they represent a reliable solution for daily professional use. Furthermore, the fastenings remain reliable under heavy conditions.
Certified quality according to EN29367-2
All NAFTA chassis clamps comply with the European standard EN29367-2 and are hot-dip galvanized as standard. This provides excellent protection against corrosion, high loads, and intensive use. Even under heavy conditions, the construction continues to function reliably. Additionally, the galvanized finish ensures a longer lifespan for the clamps.
