Features

Front-loading Post Boxes – Secure Letter Deposit Boxes

Total Locker Service supplies robust, tamper-resistant front-loading post boxes designed for secure mail and document collection. These units offer peace of mind for both indoor and outdoor use.

Built from high-grade materials and fitted with advanced locking mechanisms, our secure letter deposit boxes are ideal for flats, commercial buildings, schools, and industrial units.

The front-loading design allows users to insert letters and documents through a protected mail slot while ensuring the contents remain secure until authorised retrieval.

Each unit can be wall-mounted or recessed depending on available space and user preference.

Our post boxes are finished with weather-resistant powder coating for long-lasting performance.

Applications Across Sectors

These post boxes are widely used in apartment blocks, universities, and local authorities. Businesses can use them as external post collection units or internal document return points.

Ideal for securely collecting legal documents, signed forms, or returned keys, these boxes provide tamper-proof access with a smart appearance.

Front-loading models are especially useful in corridors or tight access zones, where rear access is not viable.

Built to Withstand Tampering and Weather

Constructed from steel or aluminium depending on model, each box resists prying, rust, and moisture. The hinges are concealed or shielded, and the drop slot includes an internal baffle to block hand access.

The lock is mounted behind the reinforced door panel and includes a two-key system for access control. Additional security options such as coded locks are available upon request.

Units can be branded or labelled according to location or use-case (e.g. 'Forms Only', 'Secure Mail').
