Knockout hole a little off... how to fix it?

As you can see above... I was off just a little on matching the hole to the knockout. The screw hole to the left exposes just a small amount of wood like the knockout does, but I feel like this isn't acceptable to leave the knockout like this with the locknut and bushing. It is secured as the locknut and bushing are sealed against 50% of the panel, the other 50% being the exposed wood. I just don't know what I can put on the knockout under the locknut to make this right, or is this acceptable?

They make metal washers called donuts.
You need from whatever size your conduit is to the next size up.
If that is a 2" nipple..... ask for 2" to 2-1/2" donuts or aka reducing washer.

Agreed, the KO is too large for the conduit. Either the reducing washers or a larger conduit is needed.

It looks to me like you used the proper concentric KO. Sometimes they are just too large for the intended size. Sometimes one too many concentric pieces fall out.

What happened basically was I was off by a quarter to half inch matching my hole in the wall to the hole on the conduit. In the process of aligning it, I figured I had knocked out too small of a hole, but I was wrong. Now it fits, but theres a gap at the top section.
That is a 1.5" conduit on a 1.5" knockout which is now a 2" knockout. I have purchased a 2" threaded PVC connector, along with a 2-1.5" adapter. I will glue those together and use like so, I will just have to drill the 1.5" inch hole in wall to 2" so the adapter fits, but using a straight saw to cut the hole down some to the proper hole.
Aye...

Why are you going to go through all that trouble? Just use the adapter ring Pete mentioned above and call it a day
