Adjustable Design for Gates, Fences & Walls
Specifically developed for integration into boundary structures, the Belgravia is ideal for:
- Gate installations
- Fence and side panel installations
- Boundary walls and entrance pillars
Its adjustable design ensures compatibility across a wide range of applications, making it suitable for both homeowners and trade professionals.
Extra-Large Opening & High-Capacity Design
The Belgravia features one of the largest parcel openings in its category, allowing it to accept larger deliveries and multiple parcels with ease.
The extended adjustment range of 10mm–250mm allows installation into significantly thicker structures than standard systems, giving installers and homeowners far greater flexibility.
Two-Part Construction for Practical Installation
The Belgravia is supplied in two sections, allowing for easier handling and installation on-site.
Due to its robust construction:
- Total weight exceeds 32kg
- Two-person installation is strongly recommended
Installation Requirements & Structural Considerations
Before installation, it is important to assess:
- Structure thickness (10mm–250mm compatibility)
- Material type (timber, steel, composite, masonry)
- Structural strength of the installation point
- Rear clearance for access and operation
As installation conditions vary:
- Fixings are not supplied
- Suitable fixings must be selected based on the material and structure
- Screw or bolt length should be chosen accordingly
Recommended Installation Approach
For best results:
- Plan installation in advance
- Install into a structurally sound surface
- Reinforce lightweight panels where required
- Ensure adequate support, particularly for gate or fence installations
Where installing into lighter structures, additional reinforcement may be required to ensure long-term stability.
