Flexible design
Flexibility and ease of installation sits at the heart of the boundary box system innovation. Discover more below:
Adjustable top section

Easily adjust the height and pitch for on-site conditions whilst maintaining loading capacity. The lid remains level to the pavement for secure installation.
Modular bayonet design

The box can be separated prior to meter installation, providing better access to the connection and minimising errors.
