Hello John. This sink can be installed as an undermount or drop-in. For UNDERMOUNT installation (the sink is under the counter therefore you do not see the rim) you will need brackets or a similar support system; sink brakes are easily available at hardware stores, Amazon, etc. For a DROP-IN (The rim is visible on top of the counter) you do not need brackets; silicone and the drain installation will secure the sink in place.
