Contacted A&L to help with getting widow spares. Had tried other sites and stores without success. We had lost a few window security inserts over the years. These inserts help guide the sliding windows and stops the window’s removal when the window is closed. Sandy, who supports the spares, helped identify the part number “105098” if you ever also need. The service and support was excellent and I felt I needed to write this as don’t often get this level of after sales support. Attached a pic if others need this same part. Thanks Hank
