Open display refrigerators, commonly used in retail environments, typically include air curtains. It can be desirable to attach air curtain guides to the front edge of shelves within the refrigerator using brackets that are capable of being attached to a ticket strip. The bracket can include teeth oriented in opposite directions that are configured to be received by corresponding grooves of the ticket strip. A screw, cam, or other transverse member can be configured to urge the teeth apart and secure the bracket within the grooves of the ticket strip.
