The new PWB-323XL economical large open wall boxes are designed to fit 16” vertically and 24” horizontally on center stud bays, simplifying AV and IT installations by providing space for routing cables, AC connections, and digital media product mounting in 3” or 4" thick walls. Integrated into each back box is flush cable-tie mounts that can be bent out when needed but lay flat when not in use to prevent interfering with equipment mounting.
