Functionality and design in a side-mounted adapter system for glass railings
The GlassFit CC-772 by Comenza is a side-mounted glass railing solution that uses stainless steel adapters/buttons. Its design helps preserve visual continuity and the flow of natural light.
The system incorporates a range of features that simplify and speed up installation while helping ensure a safe and reliable result. Thanks to its integrated adjustment and levelling devices, the GlassFit CC-772 enables precise and efficient installation and can be adapted to different mounting configurations and project requirements.
01. DESIGN
The GlassFit CC-772 stands out for its square stainless steel buttons, which give the glass railing a clean and contemporary appearance. In addition to providing a refined, minimalist aesthetic, the system incorporates several features designed to simplify installation and improve adjustment accuracy, while maintaining the required level of safety.
02. SAFETY
The GlassFit CC-772 railing system has been tested to ensure reliable performance under horizontal loads. Its performance has been verified through laboratory testing, providing professionals with greater confidence and ensuring safety for all users.
03. Easy installation
This solution has been developed to simplify installation and ensure accurate glass positioning during assembly. It incorporates adjustment devices such as Level 2D and Slot 360, together with a mechanically fixed cover and trim, making correct system installation, adjustment and levelling easier and more efficient.

Advantages
01. LEVEL 2D ADJUSTMENT DEVICE: FOR SLAB IRREGULARITIES
With the LEVEL 2D adjustment device, each adapter can compensate for slab irregularities of up to 5 mm. In addition, adjustments can now be carried out simply by removing the adapter cover, without having to remove the glass.
02. SLOT 360° LEVELLING DEVICE: FOR DRILLING DEVIATIONS
This device allows installation even when the centre of each anchor hole has deviated by up to ±8.5 mm in any direction. This makes it easier to achieve precise alignment between adapters while minimizing installation time and effort.
03. Mechanical fastening of cover and trim
The redesign of the adapter allows the trim to fit into its cover and be mechanically fastened through the set screw located at the bottom of the trim. This ensures the connection of both parts, without the need for adhesives or other types of glue, which simplifies the installation process.
04. INCREASED GLASS PANEL LENGTHS
Following the latest optimization of the GlassFit CC-772 adapter system for glass railings, the maximum glass panel length has been increased from 1,200 mm to 1,300 mm.
05. IDEAL RAILING FOR STAIRCASE APPLICATIONS
The system is particularly suitable for staircase applications, where visual lightness and space optimization are key considerations. Its side-mounted configuration helps preserve the usable width of the staircase while providing a clean installation and consistent architectural integration throughout the project.
