This Avantco bottom panel is a direct replacement for the one that came standard on your BC-72-SW or BCD-72-SW 72" white bakery case. This part replaces the pane that installs in the bottom of your bakery case cabinet. Be sure to fix a cracked or chipped pane promptly to ensure both proper food safety and a clean, professional presentation. Your 72" bakery case comes standard with 4 of these panes, and this part replaces one of them. Order 4 to replace the entire bottom.
