Hi,what I have today is how to clamp down with 1.5 inch thick under layment I am looking for a clamp that will span this distance.
We were going to put tile on then went laminate which is why we have 1.5 inch thickness,now
I have to find clamps to hold down sink,we also put a air gap unit for dishwasher boy was that
A mistake had a lot of water come out of airgap so had remove an plumb straight to drain line,I think the problem is dishwasher pumps more then airgap can handle,thank,s

Sink clamps can be found at the big box stores.
It looks like two questions here clamping down the sink and clamping down the laminate
The laminate glued doesn't need clamped. The hard board it sits on needs screwed from under the cabinet. The sink can also be sealed down with pure Silicone in it's a drop in.
