A pre-cut, pre-painted shutter door includes a pair of vertical members available
in a range of discrete or quantum heights, and having a two level slot along their
length for engaging an upper and a lower panel to form the outer portions of a
shutter door. Vertical members are preferably pre-tapped with bores to facilitate
threaded member access to engagement for attachment to the upper and lower panels.
The upper and lower panels have a curved surface to either facilitate direct manual
pivoting of the louvers or to provide clearance for an optional common actuator
bar. A louver pivot support fits within the two level slot of the vertical members
and carries a series of pre-drilled holes for pivotally supporting the louvers.
Both the vertical members, panels and louver member supports are of constant cross
section to facilitate the use of finger joints and to promote continuous extrusion-type
processing. A series of louvers have shafts which extend through pre-drilled holes
in the louver pivot supports. Louver shafts may carry gears engaging a gears fittable
within a clearance between the louver pivot supports and the more inner level of
the two level slot to accommodate a gear rack engaging the gears of the louver
shafts to provide simultaneous movement of the louvers with linear translation
of the gear rack.
