Kozza balustrade connector for round handrail ⌀ 40 mm – 180° for glass 16–21.52 mm
Description
Kozza balustrade connector for round handrail ⌀ 40 mm – 180° for glass 16–21.52 mm

Kozza balustrade connector is a precision mounting element designed for stable installation of round aluminium handrail ⌀ 40 mm onto glass panels with thickness 16–21.52 mm. The 180° version has been designed for straight handrail sections — ensuring smooth handrail guidance along long stair runs, mezzanines, balconies, terraces and in modern all-glass balustrades.
The connector consists of two aluminium halves that form a compact 'socket' embracing the glass edge and supporting the handrail from inside. This way, loads from the handrail are evenly transferred to the glass, and micro-movements during hand pressure are eliminated — the balustrade gives the impression of a unified monolith.
Key features
- Handrail: aluminium round ⌀ 40 mm — perfect fit to popular profiles, without accidental play
- Angle: 180° (straight section) — secure handrail guidance on straight runs and long balustrade lines
- Glass compatibility: 16–21.52 mm — wide compatibility with thick panels and laminated glass packages for balustrades
- Material: aluminium — naturally corrosion-resistant, suitable for internal and external applications
- Finish: matt anodised — minimalist form that doesn't visually dominate and gives lightness to the entire balustrade
- Length: 60 mm
- Weight: 0.02 kg

Why does precise glass fitting matter?

In all-glass balustrades, it's the mounting detail that determines user comfort. The Kozza connector with range 16–21.52 mm allows working with various panel thicknesses — both with single tempered glass and with laminated VSG/ESG packages. A well-chosen connector stabilises the handrail, eliminates micro-movements under hand load and evenly distributes forces on the panel edge. The result is a handrail that guides securely and a balustrade that looks professional — as it should in refined residential and commercial installations.
The aluminium construction of the connector ensures durability and weather resistance, making the element perform equally well on external terraces and balconies as in elegant office or residential interiors. Matt anodising provides a discreet, modern appearance and requires no maintenance.
