Description

A couple of years ago, a customer asked if we offered any through-the-wall parcel boxes with rear access. They also needed front and back trims to cover the opening in the wall. A few weeks later, we proudly introduced the Sierra Parcel Box with a separate letter compartment.

Manufactured from automotive-grade galvanised steel with a double layer of powder coating, Sierra provides robust and long-lasting protection against rust and UV rays.

Since its launch, Sierra has become a favourite among trade customers, builders, and gate installers, often used in side pillars or walls surrounding properties. Its design is so reliable that even if left completely exposed to the elements, it will still keep your letters and parcels dry. Available in three finishes: Black, Anthracite Grey RAL 7016, and Stainless Steel.

Please note that both our black and anthracite grey Sierra Parcel Boxes are now supplied with a matt finish, some images showing gloss finish are to show the product details only and not the finish.

Why choose the Sierra Parcel Box over competitors?

  • Inclusive Trims: Sierra comes with complete front and rear trims as standard, at no extra cost.
  • Superior Protection: Double powder coating ensures lasting protection.
  • Dedicated Letter Compartment: Keeps your correspondence separate and undamaged.
  • European Craftsmanship: Made in Europe by a multi-generational family-owned business.

A bespoke project in Canary Wharf involving the supply of 513 custom-made letterboxes, finished in a striking gold / bronze tone.

This project was all about collaboration. We worked closely with the designers, architects and the client to ensure the final result matched the architectural vision and premium feel of the building. From proportions to finish, every detail was carefully considered.

Projects like this show what’s possible when functionality meets design — creating post boxes that don’t just serve a purpose, but become part of the overall aesthetic of the space.

Designed, manufactured and supplied with the same attention to detail we bring to every project, whether standard or fully bespoke.
