ACE Extra Deep Back Boxes (#BRK1028BBX and #BRK1048BBX) are slightly deeper (8”) as compared with Standard #BBX Series Back Boxes (6”) and may be used exclusively with ACE Full and Double Wide Stage Pockets. The #BRK1028BBX and #BRK1048BBX Extra Deep Back Boxes are welded 14 gauge steel with a protective cover that is discarded when the pocket body is finally installed.
