I am ordering two replacement sashes. 28" Series 390 Channel Balance 2740 J

I need a top replacement sash as well. Can you help provide correct number for the attached top sash in the photos.

Thank You
Mark

Hey Mark. We don't carry this exact Top Sash Guide, but we believe the newer style Alenco 18-174 might work as a substitute. The screw hole is 11/32", the width of the body is 5/8" and the depth is 9/16". The balance locking lip is 1-7/32" down. This looks like it could work but take a look and see what you think.
