Through The Wall Extra Large Parcel Box – Epsilon TH

Extra Large Parcel Box for Gates & Fences & Side Panels Epsilon TH

Epsilon TH is engineered specifically for brick and masonry wall installations, offering a secure and architecturally clean solution for modern residential deliveries.

Unlike conventional through-the-wall parcel boxes that require invasive structural cutting, Epsilon TH incorporates an Intelligent Smart Regulation System adjustable up to 115mm. This enables installation within a single brick layer while preserving wall integrity.

The intelligent sliding two-part construction allows the upper section to pass through the wall aperture, while the front collar distributes fixing points evenly using perimeter mounting holes. The integrated trim frame is supplied as standard, delivering a clean architectural finish without additional fabrication.

Inside, the secure anti-theft drop mechanism prevents retrieval from the delivery side. Parcels drop safely into the locked rear chamber, which includes protective foam lining to cushion impact and reduce noise.

Epsilon TH combines parcel and letter functionality with its integrated letter flap, eliminating the need for a separate letterbox installation.

Designed in the UK and manufactured in Europe, Epsilon TH maintains high production standards while reducing long-distance transport impact.

Secure Internal Drop Mechanism

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

Interior Protection

A protective foam lining is installed at the base of the compartment to provide:

• Impact cushioning
• Noise reduction
• Additional internal protection

Refined Installation Design

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

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

This configuration allows for accurate alignment and a consistent installation result across different materials and structures.

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.

Why Epsilon TH Stands Apart

• One of the largest parcel openings in its category
• Adjustable for 10–115mm panel thickness
