How to Measure: With Upstand

If the bottom track has an upstand, then the measurement should be taken from the top of that upstand to the top (highest point inside the top pocket). Next, subtract ½ of the depth of the top track and that would be the height to order. Example: If your top track is ¾” deep and your measurement from the top of the sill track upstand to the top of the top track is 71 ½” then you would order 71 1/8”.

How to Measure: No Upstand

If there is no upstand, then the measurement would be from the top of the bottom pocket (top of the outer leg not down in the pocket) to the top (highest point inside the top pocket) and subtract 5/16 of an inch and that would be the size to order.

For Width:

For the width, the measurement would be from the farthest point inside the side pocket to the edge of the glass then subtract ½”.
RiteScreen cannot be responsible for the screen if it does not fit.
