I've recently installed a replacement Gainsborough entrance set.
It was the Gainsborough Matt Black Trilock Contemporary Angular Double Cylinder Leverset.
The instructions seemed to be for a different model but were reasonably easy to interpret : frustrating though.
The entrance set seems to be working 100% but I have this part leftover.
Do I need to reinstall it with the left over piece?
If so, where does it go?
