Hi Sifus,

Recently, my contractor installed my granite sink with sealant only for undermount design). They cut a very big hole (way to big) on the wood plank and now I am not able to install clips for additional support on the granite sink.
Worried if the sealant one day wear off and the sink collapse. Any advise?

Ideally the sink plus 10kg worth of plates need support.
Usually done with custom ss bracket overseas with adjustable height of sink so the sink rest on the support bracket and bracket mounted to the countertop or cabinet carcass. U can achieve similar with wood planks 2x3 or 2x4in
