b&q drawpack

[Graftershave]

He means the pan bars that bridge the back of the draws to the front, well I think so, seems something the wrong size, nothing I've come across they normally attach pretty easily on a B&Q kitchen, not that I do many to be an expert on the matter, I know the draw boxes are garbage, the plastic clips that hold the fronts on are terrible and the adjustment is neither here nor there.

Measure the distance between the points it connects, measure the pan bars. There might be shorter ones.
