Abstract: There has been provided a drop-in cutting board assembly for an apertured countertop, wherein a vitreous cutting surface is located over a backing or strengthening member. A T-band holds the cutting surface and backing member together by means of a pair of opposed flanges joined together by an annular band located about the periphery thereof. An outwardly facing proportion of one of the flanges engages a peripheral margin of the countertop aperture to support the assembly in place and a channel formed integrally of the annular band extends below the countertop. A latch engages the channel and has free ends for engaging both the rearward portion of the backing member and the countertop for securing the assembly firmly within the aperture countertop.
