Inside:



STEP 1:
Measure the inside width at 3 locations - the top, middle and bottom. Record the smallest of the 3 measurements. This is yourordering width. We will make the necessarydeductions (approx. 1/2").
STEP 2:
Measure the height at 3 locations - the left side, middle and right side. Record the smallest of the 3 measurements.
We recommend taking 1" off of this measurement to ensure panels are off floor / sill. This is your ordering length and will be the measurement from the top of the track to the bottom of the panels.
