Shadow flap

Shadow valve

The Oostwoud Shadow flap stands for exclusivity, craftsmanship and timeless design. Designed by Lieven Bekaert, this letterbox flap combines sophisticated design with high-quality materials and carefully crafted details. The result is a flap that seamlessly combines functionality and aesthetics.
The flap is made entirely of bright polished stainless steel 316, a durable and corrosion-resistant material that can withstand the harshest weather conditions. The subtle sheen of the steel gives the valve an elegant, modern look that suits both classic and contemporary architecture.
