How to fix a split sliding door

It is not uncommon for the bottom leading edge of a sliding door to split away. The roller assemblies have been housed in the bottom so the timber is thin. Doors are often made in layers, so if the door comes off its track it will invariably land on an edge, and the face of the door could split away. This is made worse if the bottom of the door gets wet during rainy weather. The roller assembly will likely break away as there isn't sufficient timber to hold the screws. However, all is not lost.
