A:AnswerNowhere in the product specs does it claim to be CL2 OR CL3 rated and according to Dynex's website, it is not rated for in-wall installation at all.
As a couple of the other replies note - in a rather foolhardy manner - it can of course literally and physically be used inside walls, but that would be really stupid. Electrical and fire codes - and wire safety ratings - exist for very good reasons; only fools ignore them when they apparently don't even understand the reasoning behind the ratings in the first place.
