This Avantco 178CBEB29380 21 1/2" x 1 1/8" hookless divider bar is a direct replacement for the one that came with your CBE-48-HC chef base. This part is used to keep even spacing between the pans in your unit's drawers for clean, efficient storage of ingredients and supplies. Since it doesn't have hooks, this divider bar can be moved around on your unit instead of locking into place. This helps you accommodate different pan sizes.
