No Stud Speaker Hangers install into drywall and hold speakers up to 30 lbs. each without damaging walls. Two interlocking aircraft-grade aluminum brackets provide extraordinary strength. A foam pad on the wall bracket protects walls from scuffing. Simply mount one bracket on the speaker with included screws, then install the wall bracket with a hammer, tapping in tiny picture nails. These nails leave only pinholes upon removal An included level guarantees straight installation.
