Use these shelf clips to mount ClosetMaid ventilated wire shelving to a back wall when you are installing a closet system using the traditional fixed-mount installation method in drywall. The clips anchor directly into the drywall and lock the back of the shelving into place, using 1-shelf clip every 12 in. and 1 at each end of the shelf. Add metal shelf supports (sold separately) to hold the front of the shelf. Color: White.
