Thanks HipKat. It appears I'm out of luck. I called FJB at 860-529-6350 and they said because of the windows age (10+years) they don't have parts and to call Shulco at 860-666-0505. I understand from this site that Shulco bought out the Insul-sash factory. Note the FJB website name: http://www.insulsash.com/index.html
- Shulco said they don't have Insul-Sash parts since Insul-sash has gone out of business. They said to try some local window company for parts. I'll probably just try and fabricate something to make the window more usable. Would have been nice to find a real part. Great info on this site, very helpful in gaining some understanding of windows + the business.
