Siedle Steel
Six millimetres: A letterbox can be this flat. The housing disappears into the wall, leaving only the plane front panel visible with its solid grip rail. From the inscription through to access control: Combinable with every conceivable function.
Configuration examples
Pass-through letterbox
If the mail is removed from the back, there is no lock to interrupt the minimal design look.

Letterbox system made of brushed stainless steel, fitted with an intercom unit and engraved call button.
The Steel design brings out the aesthetic merit of the material to optimum effect. Letterboxes, lighting and door communication combine to create the perfect ensemble exuding elegance and sophistication in the entrance area.

Stainless steel removal door for pass-through letterboxes
The removal door at the back including the removal shaft and frame can optionally also be provided in stainless steel. While the high-grade material enhances the optical appeal, the changed design also permits simple plaster compensation with the subsequently mountable and displaceable removal door. In addition, an all-round sealing lip protects against drafts.
Mail removal from the front
Here too, the wall accommodates the letterbox housing but without breaking through to the back. The mail is removed from the front.

Same configuration, totally different effect: The character is determined by the material.

Perfect geometrical alignment also when arranged in horizontal formation. The inscription appears easily legible, illuminated by the surface area light. Its luminous intensity is sufficient to also light up the letterbox.
