Product 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.

    Perhaps heavier than I expected but indicative of the quality.

  • Debbie Robey Confirmed by Feefo

    Great quality metal box. Ideal for letters and small parcels. Our box is being placed through metal railings on our front wall . The box can be accessed from the back by a key.

  • Trusted Customer Confirmed by Feefo

    Perfect - it did need to be wedges inside the wall as the face of the letterbox was not deep enough for the thickness of our wall. Thankfully our builder did a great job

    Response from Amy

    Thank you for your feedback! We’re glad to hear everything worked out and that your builder was able to install the letterbox successfully.

  • Jason Phillips Confirmed by Feefo
