Howdens Kitchen

Hi All,
I am fitting a howdens kitchen and seem to be some fitting kits missing from the base units.
I have the following units:
1000mm corner unit
1000mm sink unit
1000mm base unit
500mm drawer unit
600mm base unit x2
500mm base unit
600 oven unit

The fitting kits I have are labeled;
FITNB10HLB x2
FITNB6HLB x2
JF1NBDP x1

I am thinking that the FITNB10HLB is for the 1000mm base units and the FITNB6HLB is for the 600mm base units,
But don't know what the JF1NBDP is for.
Anybody any ideas?
