Gates and Fences and Side Panels Large Rear Access Parcel Box Adjustable 10–115mm – Epsilon GM
Gates and Fences and Side Panels Large Rear Access Parcel Box Adjustable 10–115mm – Epsilon GM
The Epsilon GM is a high-capacity gate and fence mounted parcel box designed specifically for secure installation within timber, aluminium, composite and steel panels. Engineered in the UK and manufactured in Europe, it offers structural reliability, installation flexibility and modern architectural styling.
Designed with one of the largest usable parcel insertion openings in its category, Epsilon GM allows larger deliveries to be deposited securely without compromising safety. The integrated letter flap removes the need for a separate letterbox, delivering a clean and efficient two-in-one solution.
Adjustable Installation System (10–115mm)
The sliding lower section enables installation within panel thicknesses ranging from 10mm to 115mm, making it suitable for:
- Wooden gates and fence panels
- Aluminium and slatted gate systems
- Composite fencing
- Steel and fabricated panels
- The two-part construction slides and fixes securely into position, allowing precise adjustment to suit varying gate builds.
Secure Drop & Rear Access Collection
Parcels are deposited through a controlled internal anti-theft mechanism. Once inserted, items drop into a locked rear-access compartment, preventing retrieval from the delivery side.
The internal chamber includes a protective foam lining to reduce impact noise and provide cushioning.
Intelligent Structural Mounting
- Front collar with perimeter mounting points
- Integrated trim frame included as standard
- Adjustable internal support bracket for improved weight distribution
- Option to secure rear section directly to the panel for additional reinforcement
The overlapping upper and lower sections help reduce water ingress while maintaining structural integrity.
