Why choose Sperryn’s 2nd stage meter box kit?

1. The meter bracket has been specially designed to work in all meter boxes and ensures a BS6400 compliant installation. This provides increased confidence that the solution will address all box types without having prior knowledge of the installation.

2. Low profile elbows ensure a compact size envelope and combined with a flexible joint ensures less manual effort for the installer to manipulate the flex hose, reducing time and associated health and safety issues.

3. The compression connection on the outlet kits for dry boxes means there is no requirement to solder several joints, again reducing time, particularly when experiencing inclement weather conditions.

4. Also, a common issue relating to flux corrosion within the meter installation will be eliminated, reducing health and safety concerns post-installation and re-visit costs.

5. Connect Lid enclosure – New Easy to fit kit ensures lid closure even in the most challenging box types including Connect and Wet boxes.

6. Pressure drop tested in compliance with BS6400.
