150mm Center Guide

This is a little template I made so you can mark out 150mm centers for installing thermostatic showers (or for anything else that needs to be set to 150mm centers)

The wall for the outter hole is 25mm.

The internal wall for the inner circle is 4mm.

The outer wall for the inner circle is 6mm.

you can use the template to place your spirit level on top to ensure a plumb setup and then mark you drill holes easily.
