I have had many experiences with this before, it is best to use 300 of it's fine, you can use a good quality plastic bag and then fill it with other plastic wraps into a ball from the mouth of 400 into the mouth of 300 with a screwdriver, be sure to see it just on the side, (note that this side of nearly 300 mouths must be smooth and full) may as well be 300 outlets, and then use a good mildew silica gel around the periphery to hit a layer on the plastic bag, the original 300 exit cover plate from all around with a flat-edged screwdriver to knock off, In the 400 outlet and then fill the flat with plastic, inside and outside the silica gel can be, must wait for the silica gel to dry before use, such as not at ease and wait for the dry water test before it is practical,

You're better off using a single hole. The double hole is still a bit of a hassle.
