The longitudinal adjustment can be resolved by adjusting the overlapping of the two cavity tray elements.

The Cavity Tray system also provides Inner and outer corners. The adjustment of these elements is similar to the straight cavity trays, simply using the overlapping.

A stop-end element can be used at the end of the cavity tray if necessary. This element stops the water flowing laterally and can be adjustable as well.
