✔️ INSECT FREE IN 3 MINUTES: unfold, take out, clamp in – the telescopic insect screen with frame in anthracite is mounted as quickly as no other mosquito screen. No tools, drilling or screwing. Immediately effective against mosquitoes, wasps, flies, spiders etc. ✔️ FLEXIBLE CUSTOM-MADE SOLUTIONS: Whether it’s a small basement window or a double-hung window – the frame can be extended to the desired size for internal window dimensions ranging from a minimum width of 70 cm to a maximum of 115 cm and a minimum height of 80 cm to a maximum of 135 cm – without the need for measuring. ✔️ NO CUTTING: since the mosquito net is already integrated into the frame with this telescopic insect protection system, it does not need to be cut to size - this makes the installation child's play and there is no more annoying waste. ✔️ STRETCHY NET: The weather-resistant mosquito net made of high-quality, stretchy and resilient fabric adapts to the frame size when removing the adjustable fly screen and retains its shape, even with repeated assembly and dismantling of the grid. ✔️ OPTIMAL TRANSPARENCY: the black special fabric blends almost invisibly into any window without darkening the rooms. The window grille is particularly breathable - ideal for ventilation or sleeping with an open window without blind., Manufacturer: DS Produkte GmbH
