A:AnswerRegrettably, the LG 2.1ch 300W Sound Bar with Wireless Subwoofer and Bluetooth® Connectivity, Model # SK4D does not have slots that are designed for brackets that allow you to mount it to your TV. You might be able to find some shelves that you can mount on the wall right under the TV that will be able to hold the unit. These can be found at retail outlets like Best Buy or through online retail sites. ^CP
