Just a quick note on the new k4fins slot box blankers (apologies for the grainy pics off my phone).
These are designed to be finished off by the end user in order to get a perfect fit and the desired tab to remove them with.
As you can see in the pics there’s a very thin tab on either end. These can be trimmed/shaped to match your slot box perfectly. I actually cut one end off completely and left the other to fill the gap at end. This then gives you something to get a blade under to prize them out.
Oh, I now have a Simmer 75 Fly 🙂
