Description
Black flat end cap for 40×40 mm PV mounting profile – type 3 LLDPE

The type 3 flat end cap for 40×40 mm mounting profiles is an essential finishing component for any photovoltaic installation based on aluminium profiles. Fitted onto the open ends of profiles, it effectively protects their interior from the ingress of rainwater, dirt and contaminants, which could accelerate corrosion of the steel connectors inside the profile. Made of black LLDPE polyethylene, the end cap remains fully flexible even at extremely low temperatures and is highly resistant to degradation caused by UV radiation. Thanks to its flat design, the cap does not protrude beyond the outline of the profile, ensuring an aesthetic, professional appearance for the end of the mounting rail. Its low weight of just 12 g means it does not add to the load on the structure, while its precise dimensional fit ensures it holds firmly in the profile.
Advantages of the end cap in everyday installer work
- Protects the interior of the mounting profile from rainwater, dust and contaminants
- LLDPE polyethylene remains flexible down to –100 °C and is resistant to UV radiation and weather conditions, guaranteeing long-term durability outdoors
- Flat design does not protrude beyond the profile outline
- Quick installation by sliding onto the end of the profile – no tools or additional fixings required
- Improves the aesthetics of the photovoltaic installation, giving it a finished, professional appearance
