Designed for new work, VB1 is easy to install on most plastic or steel single gang boxes. Use the supplied #6-32 screws to temporarily hold the VB1 in place during the installation of 1/2" or 5/8" drywall. Once the drywall is installed remove the #6-32 screws and install the device. Secure device box to framing member per manufacturer’s instructions. You can also fasten the VB1 to the framing member using the flashed-over holes in the flange.
