I have a single hung window with a broken right side tilt mechanism. I have attached a picture (IMG_7068) of the label on the sash which says NVR2 NVR Bldg Prods - Thurmont 1800J Single Hung 33 3/4 x 76 3/4. The information I received when I bought the house new in 2003 said the windows were Patriot.
The part I need is the gray 'bar" and pivot piece as shown in IMG_7064. The bar has 36C BSI or BS1 stamped in it as shown in IMG_7069.
Can you please assist me and tell me exactly what part I require? From what I can deduce from trying to identify the part on the site it is a channel balance.
Thank you.
