Available in two sizes, our weatherproof High Security Post Boxes have been made with outdoor environments in mind. Designed to protect letters and small packets from theft, these Post Boxes also act as part of our One Key Solutions range, offering the potential for integration with existing ‘single key’ systems, increasing the flexibility of security systems without increasing the risk.

High Security Post Boxes

Ideal for mounting on any flat surface, the High Security Post Box is constructed from high quality 1.5 mm galvanised steel and finished with a powder coat paint that is incredibly hard-wearing, maintaining its finish against weather and rust. To protect against rattling in strong winds, noise dampening materials have been incorporated to keep noise to a minimum.

These Post Boxes can easily accept letters and parcels via an A4 letter slot on the top. This slot features a steel flap to protect contents from the elements, and a side-hinged door situated on the front allows for easy removal. The lock bolt is protected with a robust anti-rip plate to prevent prying.

Standard Post Boxes

External Post Boxes have steadily increased in popularity recently for both domestic and commercial properties. The success of the High Security Post Box range has allowed us to develop a brand-new range of Standard Post Boxes that may suit those with different security needs.

With high-grade steel, powder coating and a high-quality cam lock, these fabricated Post Boxes are built to the same exacting standards as our ‘System’ key cabinets.

Available in two sizes, each come with the option of front or top loading and accept A4 sizes comfortably. To protect against rattling in strong winds, noise dampening materials have been incorporated to keep this to a minimum.
