I am not convinced by that solution, if it fits the opening I see the point, but it is now just something else that could break / go wrong, plus you are effectively making the main intake opening smaller.

The box should of had a lip molded, not sure there is a real solution unless they redesign it, but due to low demand (I hope I am wrong) it very likely won’t happen.

The good news is that is not the end of the world as it can be made to work perfect as is with minimal cost and effort.

I may order my “fix” kit just in case, but almost certain I wont use it.
