Garvin 52181-VTBAR Description

3-1/2 inch deep 4-in square junction boxes with ceiling grid span bars and (8) 1/2-in & (4) 3/4-in side knockouts and (3) 1/2-in & (2) 3/4-in bottom knockouts are installed in ceilings where extra depth is needed for dimmers cameras speakers strobes signals and other electrical and electronic devices. They slide on mounting bars and adjust four different ways for perfect location on ceiling tiles. They work with both standard and revealed ceiling tiles. Their adjustable screws allow box depths to be changed for a perfect flush mount on ceiling tiles. Garvin’s labor saving design eliminates the need to awkwardly install boxes and extension rings to accommodate deep devices.
