Need vertical line between two columns

I’m trying to insert a gray vertical line between two columns on several of my pages. I haven’t had luck just using a sidebar instead so I’d rather insert the line but not sure what code to use to do so. The link to the page in question is below – current code is below. I’d like to insert the line between the text on the left and the images on the right.
