Separate Letter and Parcel Compartments

The Sigma features separate compartments for letters and parcels, so everyday post is kept apart from parcel deliveries. Letters are delivered through the dedicated letter slot into their own compartment, while parcels are deposited through the separate parcel opening and stored independently.

Ideal for gate and fence installations, this design keeps different types of deliveries organised while allowing convenient collection from the secure rear-access side.

Subtle Brilliance, Same Reliability

This premium edition of our bestselling Sigma box was developed for customers seeking the same robust functionality — but with a refined visual edge. The brushed stainless steel front panel adds a layer of sophistication to an already trusted design, making it a favourite among architects, premium developers, and homeowners who appreciate detail.

Built in Europe by our long-standing partner — a third-generation manufacturer with blacksmith origins — this box is engineered to perform through rain, frost, and constant use. Exclusively designed by Parcelbox4you, it carries the same thoughtful features as the original Sigma, reimagined with a material finish that quietly elevates the everyday.

For those who believe function should never exclude beauty, the Sigma with stainless steel front delivers on both fronts — style outside, strength within.
