Wire clamp in blue box

The local hardware store only had the blue plastic outlet boxes that were 2"+ deep for some GFCI's I'm putting in... no metal that deep. The boxes have 4 knockouts for the wires, but I don't see how to secure the wires to the box.

Do I need to?

The knockouts are not knockouts the wire is pushed through the slot and the plastic tabs are supposed to prevent the wire from pulling back out

no, the plastic boxes don't require internal wire clamps they just slide in the holes. The correct way to do it is to turn the tabs (that are covering the holes) to the side so you can neatly place two wires in the knockout, most people just break off the tab completly.

Your life will be simpler if you find another hardware store, one that sells 3" deep boxes.

Don't forget to staple the cable to the stud within 8" of the box.
