(50 mm) in width when measured as shown in Fig. 1, sketch (a). On sinks with integral rims, flanges shall not be more than 292 in. (64 mm) in width when measured as shown in Fig. 1, sketch (b).
2.3.2 Kitchen Sink Ledges (See Para. 1.6 for Definition). Ledges at the back of kitchen sinks shall be flat, rigid, and otherwise suitable for effective installa- tion of fittings (see para. 4.2).
