Outdoor Parcel Drop Box – Architectural Through The Wall Installation – Epsilon TH

Important Pre-Purchase Notice
We strongly recommend downloading and reviewing the installation instructions prior to purchase. This will allow you to assess suitability for your gate, fence, or wall structure and ensure a smooth installation process.

 

Epsilon TH has been developed for refined architectural integration where proportion, precision and security matter.

Its Intelligent Smart Regulation System allows controlled wall adjustment up to 115mm, enabling installation within a single brick layer without structural compromise. The intelligent sliding two-part construction ensures controlled fitting and balanced weight distribution.

The integrated front collar with perimeter mounting holes delivers structural stability while preserving masonry integrity. A clean trim frame is included as standard, ensuring a finished façade without visible mounting disruption.

Internally, the anti-theft drop mechanism secures parcels within the rear retrieval chamber. A protective foam lining cushions deliveries and reduces operational noise.

With one of the largest usable insertion openings in its category and integrated letter functionality, Epsilon TH combines elegance with practicality.

Designed in the UK and manufactured in Europe to exacting standards.

Secure Drop Mechanism

Parcels are deposited through a controlled internal anti-theft system. Once inserted, items drop securely into a locked rear-access collection chamber, preventing retrieval from the delivery side.

A protective foam lining at the base of the compartment provides cushioning, reduces impact noise, and enhances internal protection.

 

Refined Installation Design

The installation process has been engineered to deliver precision and a clean architectural finish:

• The upper section slides seamlessly through the prepared aperture
• The front collar is secured using perimeter mounting points
• An integrated trim frame (included as standard) creates a refined, built-in appearance

The two-part configuration allows for accurate alignment during installation, ensuring a consistent and professional result across a wide range of gate and panel types.

Installation Requirements & Structural Considerations

This parcel box is a robust, heavy-duty unit (approx. 27kg+). It is essential that the intended installation surface, whether a gate, fence panel, or structure, is capable of safely supporting this weight.

Please ensure that hinges, fixings, and supporting materials are structurally sound and suitable for load-bearing applications. Certain lightweight gates or panels may not be appropriate without additional reinforcement.

Failure to assess structural suitability prior to installation may result in damage to the product or mounting surface.

 

Recommended Installation Approach

For installations on gates or fence panels, we recommend providing a supportive base beneath the parcel box—such as a plinth, timber support, or solid foundation (e.g. concrete or brick).

This helps distribute the weight effectively and reduces long-term stress on hinges and mounting points.

For built-in or wall installations, the surrounding structure typically provides sufficient support; however, for thinner panels or lightweight constructions, additional reinforcement should be considered.
