Installing a stainless Steel or similar decorative sink can be a challenge. There are many ways to accomplish this but we think this is probably the most effective way. The stud is welded to a 1" base with holes in it. Locate and place your sink this the top upside down if possible. Apply a bead of Silicone to the sink where it meets the countertop and place it. Apply several Sink Setter washers around the sink using epoxy. Make sure the epoxy pushes thru the hole to creat a permanent bond.Many fabricators use seam adhesive but it is not recommended as it is too brittle and vibration from a disposal can make the bond fail. Once the epoxy has dried apply Sink Clips (available separately) and snug down the wingnut ill tight.
