I am installing my second FCU of the day. On the first one, the cut out came out perfectly first time. This is the cut-out on the rim of the FCU that lets you run a flex into the unit.
The second one was not so good. I tried using a stanley knife (which worked fine on the first one) and ended up with a face full of plastic shards! Then I thought "I will nibble it out with some snippers". One nibble and the corner shattered off.
One trip to Wickes later and I have another FCU (albeit now a Wickes branded one).
My question is: what is the correct method to remove the cut-out? I am using a brand new Stanley blade so it definitely isn't blunt! I don't have a rasp or file to hand unfortunately, or I would try that.
