+ A two-piece Style 20 Recessed Escutcheon with 1/4 inch (6.4 mm) of recessed adjustment or up to 1/2 inch (12.7 mm) of total adjustment from the flush pendent position.
The adjustment provided by the Recessed Escutcheon reduces the accuracy to which the fixed pipe drops to the sprinklers must be cut.
