Same size as rectangle grid tray pictured above, only tray has a square grid. Measures 13.5'' X 10'' X 1.5'' deep. Makes 24 bars measuring 2 1/4 x 2 1/4''. Each bar is approximately 4 ounces. This tray mold is ideal for volume production. The grid makes cutting a breeze and ensures bars are uniform in size. Why the rounded corners on the large slab trays?
