✔️ 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 to measure: whether small cellar window or large double casement window – the flexible telescopic frame can be adjusted to the desired size (min. 73 x 83 cm - max. 120 x 140 cm) and install without cumbersome measuring. Individual mosquito repellent without planning effort. ✔️ 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
