Description
Kozza – EPDM gasket for aluminium glass clamp 20–21.52 mm, 50 m roll, black

Kozza gasket for aluminium glass clamp is a professional mounting element ensuring stable and secure fitting of glass with thickness 20–21.52 mm in aluminium clamps for all-glass balustrades. Made from durable EPDM rubber (ethylene propylene diene monomer), it guarantees years of durability and reliability in varying weather conditions. The 50 m roll allows completion of even large projects without the need to join multiple short sections — real time savings on site and less waste.
The gasket profile is U-shaped and is placed directly on the edge of the glass sheet, then the whole assembly is inserted into the aluminium clamp. Thanks to the slight narrowing of the entry opening at the bottom (21.5 mm) relative to the internal width at the top (22 mm), the gasket securely grips the glass and won't slip during installation.
EPDM rubber – reliability in all conditions
EPDM material is widely used in construction and industry due to its exceptional resistance to external factors. The Kozza gasket maintains full flexibility and functionality both during severe frosts and in hot conditions:
- Operating temperature range: from −40 °C to +100 °C
- Resistance to UV radiation, ozone, rain and snow
- Resistance to typical chemicals — detergents, alcohols, mild acids
- Long-term flexibility without cracking and hardening

Application
The gasket is intended for use with aluminium clamps for all-glass balustrades. It works well wherever secure and aesthetic fixing of toughened or laminated glass sheets with thickness from 20 to 21.52 mm is required — on balconies, terraces, staircases and building exteriors. It protects the glass edge from mechanical damage and eliminates vibrations in the aluminium profile.
