An insert, also called a power pack or liner, is the working part of a hood with no outer shell. It fits inside a custom wood or plaster hood, or into a cabinet, so the hood can match the kitchen. Check the cut-out size the insert needs, not just its nominal width: a 30 in insert is often a few inches narrower than that.
