SWC 52181-BLNK 4 Sq 3-1/2in xtr Dp

Blank 4 in square 3-1/2 in deep junction boxes are installed in walls and ceilings where extra depth is needed for dimmers cameras speakers strobes signals and other electrical and electronic devices. Blank boxes have no holes or knockouts allowing the installer to have customized knockout and hole configurations depending on their installation requirements. Garvin' labor saving design eliminates the need to awkwardly install boxes and extension rings to accommodate deep devices.
