Please be aware that this supporting article is a subset of a much larger article Outdoor CSAA/PSCA Installation. Refer to the main article for expanded IOM installation details for each ship with crate part.
Stacked flashing is used to seal the joint between the lower and upper sections of an Outdoor Stacked unit, CSAA/PSCA Size 3-50. The seal is completed by adding the gray butyl tape provided in the ship with kit between the stacked flashing and the upper level base rail. Stacked Flashing (SFLASH_###) will be custom formulated parts numbers for every unit, so no 2 units in assembly, or even on a same sales order will be identical. The flashing pieces must be mounted in the location they were designed to cover.
If Stacked Flashing is missing, or damaged, follow the process outlined Expanded Short Ship.
