The Letterman IV is the reduced edition of the classic Letterman by Radius Design. It offers the typical advantages of the Letterman-series, but it is absolutely opaque.
Radius Design presents a letterbox that keeps curious glimpses away with the Letterman IV. The design of the classic Letterman is still the same, but not everyone wants to show his post to the neighbors. The Letterman IV helps in this case! Its elegance replaces the missing bulls-eye – the Radius Letterman IV furthermore bribes with its design and practical utility.
Moreover the post is protected from wind and weather by the wide clap. The Letterman IV is also available with a supporting tube.
