vertical tube forcefield?

[nop277]

So I've got a fortress in the nether I've been trying to protect from Ghast, and I put up a forcefield but it keeps demolishing my elevator track I use to get up and down. I want to put a hole there in the forcefield and I heard the tube forcefield can put holes in the dome forcefield but I cannot get it to make the tube vertically instead of horizontally. I tried turning it using a wrench but that didn't work, is there any way to do this or a better way to put the hole in the forcefield?
