B-Line BB70 Box Support Bracket

The unique interlocking design of the BB70 box support bracket & BB70E bracket extender increases the rigidity of the system.  The patent pending design adjusts to stud depths of 2.5” to 6″ using these two parts, greatly reducing the complexity for stock locations and job-site installation.  The bracket is compatible with Rapid Ring™ pre-fab ring, adjustable plaster rings, the BBFS-18 floor stand and the BBCC cable containment clip.
