This water-tight, wall- or door-mounted mail slot is a functional design that won’t compete with architectural forms. Mail is delivered by pushing on the center panel, which pivots on a hinge that’s carefully crafted for a satisfying weightiness. This spring-loaded hinge keeps the slot closed when not in use. The solid construction of the Line One Letter Plate is made of heavy-gauge stainless steel that can be paired with Neutra Modern House Numbers or our modern doorbells to complete the entryway experience. Atelier 522 is a creative agency made up of architects, interior designers, product designers, graphic designers and photographers. For more than 60 years, the Atelier has been combining high-grade metals with quality design and an element of surprise. Hardware not included. To order a back plate (not included), please call us at 1.800.944.2233. Made in Germany.
