Inside Mount Installation
To find width:
Measure the opening across the top where the headrail
is to be installed from inside of jamb on left to inside of jamb on right.
Round the measurement down to the nearest 1/8".

To find length:
Measure from the inside top of the
opening on the left, at the center, and on the right to
the sill; round the measurement down to the nearest
1/8" and note the smallest dimension.Do not make
any allowances: the factory will make all adjustments
so the headrail will fit the opening properly and the vanes
will clear the sill by 1/4" to 1/2".
