Not unless there is about 2” of airspace behind the drywall, between the back of the drywall and the concrete block. And you have to have unobstructed vertical access inside the wall between the upper and lower ports so you can pull the cables down, so any horizontal lath, cross-members, or fire-breaks will prevent cable access. You will probably have to run your cables on the outside of the wall and conceal them with a cover or paint-matched plastic channel.
Sorry, there was a problem. Please try again later.Only if the space between the concrete and sheet rock allows for sufficient room to run cables and proper seating of wall kit. In most cases you will not be able to fit wall kit.

Sorry, there was a problem. Please try again later.Is the drywall against the concrete block? You need the standard electrical box depth to install the product.
