the B&Q cabinets come with two ****ing little 2" pieces of that bar

Despite this there must be 100,000s of cabinets fixed to the walls with
the supplied fixings and very little reported evidence that they are
falling off walls.

I don't say they're likely to fall off, just that the longer lengths are
easier to fit and get a whole run straight and/or level, and avoid
needing to drill for screws/plugs in inconvenient places.
