This Avantco bottom panel is a direct replacement for the one that came standard on your BC-48-S 48" black 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 48" bakery case comes standard with 2 of these panes, and this part replaces one of them. Order 2 to replace the entire bottom.
