Helton/FlexiForce has improved the design of their residential Center Support Bracket. Part number: BKT-CSB-13-ADJ. The bottom two horizontal slots have been replaced with one vertical slot. This modification has been made in order to increase the rigidity of the bracket by moving the mounting slot closer to the flange and to provide installers with increased vertical adjustability when installing their torsion assemblies. Please contact your Sales Representative for more details.
