Must be something to hide the cord going down the wall to the outlet.Perhaps
Some molding or cable cover?

Home Depot and Lowe's have a variety of cord covers. I just installed a flat one, painted the wall and can hardly see it. Most new construction has wiring in a recessed box.

Oh that is the name cord cover. Thanks
