The S4 RooFit Universal Frame is the patented base plate at the heart of the S4 in-roof mounting system. It forms the core mounting point that every panel connects to, and is engineered as a single universal component compatible with all panel sizes, in both portrait and landscape orientation.
By replacing multiple part references with one patented base plate, the frame eliminates layout errors, reduces the number of components an installer needs to carry, and speeds up on-roof assembly considerably.
Portrait/Landscape
Orientation
Patented Universal Base Plate
One frame accommodates all supported panel sizes, so stock complexity and installation time are both reduced compared with panel-specific mounting rails.
Universal Compatibility
Fits all panel sizes in portrait or landscape orientation without needing separate part numbers.
Simplified Panel Replacement
If a panel is replaced with a different size in future, only the module changes — the frame stays in place.
Integrated Waterproofing
Designed to work with the system's flashing components so no separate top flashings are required.
Reduced Component Count
Part of a wider system built from just five core accessory types, cutting logistics complexity.
Mixed Orientation Support
Portrait and landscape panels can be combined on the same roof to make best use of available surface.
Long Service Life
Engineered for a design life exceeding 25 years, backed by a 10-year warranty.
