CDA Buying Advice – Hobs: What is a bridging hob?
The induction hob models HN6731, HN6841, HN9611 and HN9840 all feature one or more ‘bridging zones’ on the surface. This large cooking area can be used separately by switching on either the front or back part of the zone.
Alternatively, both zones can be switched on together to form one, extra-large cooking area. The bridging function makes it easy to use large or oddly shaped pans and casseroles.
