The Big Foot Multi Frame XL is an extremely robust and flexible mounting system for flat roofs. It has been developed for quick and easy installation and ensures maximum stability as well as unrestricted roof usability – even when installed.
Thanks to the three integrated crossbars and the infinitely expandable design on both sides, the system can be optimally adapted to different requirements. Each support foot is individually height-adjustable and removable if required, allowing precise alignment even on uneven roof surfaces. The large footplates ensure even load distribution and protect the roof surface.
With a maximum load capacity of 500 kg the Multi Frame XL is ideally suited for demanding applications. Inclined anti-vibration mats as well as a higher construction version are optionally available to meet additional requirements.

The Big Foot Multi Frame XL Extension provides a durable, flexible, and high-quality solution for extending flat roof mounting systems.
Mounting base for easy installation of air conditioning units or cable trays with versatile application options on flat roofs or outdoor areas. High load-bearing capacity and wind resistance ensure reliable performance under various weather conditions. The set includes four hammerhead screws for mounting. Please order sufficient rubber mats or construction protection mats as a base for flat roof installation.
The mounting base enables easy and secure installation of air conditioning units and pipework on flat roofs and in outdoor areas. Thanks to its high load-bearing capacity and excellent wind resistance, it is designed for reliable use under varying weather conditions.
The set includes four T-head screws for professional installation. For installation on flat roofs, the use of suitable rubber or construction protection mats as a base is recommended.
Please note: For smaller air conditioning units (e.g., up to approximately 3.5 kW cooling capacity), a 400 mm long base may be sufficient for installation, but it does not provide adequate wind load protection. For stability and safety reasons, a minimum length of 600 mm, ideally 1,000 mm, is recommended.
This roof inlet is designed for the safe and reliable routing of cables and wires on flat roofs. Its corrosion-resistant construction ensures long-term durability without rust or leakage.
The wide base surface allows for a secure and watertight connection to the roof membrane. Manufactured from lightweight 2 mm aluminium plate, the unit combines structural stability with ease of installation.
The interior is smoothly rounded beneath the protective hood to protect cables and insulation coatings from mechanical damage. With a generous passage opening of 125 × 125 mm and a height of 600 mm, the roof inlet provides ample space for organised and protected cable routing.
For enhanced thermal insulation and condensation protection, optional insulation using Armaflex® insulation materials and technical foam is available. This optional insulation improves energy efficiency and provides additional protection for sensitive cables and conduits, particularly in demanding climatic conditions.
