I attached parts picture to let you recognized/compare, then give me the right parts number which I can correct order.
Also, I look on your website I seen "Nylon (black)Top Sash Guide used with series 390, production code: 18-009". I don't know that compatible with my "Channel Balance Series S350-28", isn't it?
In the parts picture I attached, it contained a little retangular sharp part, they're snap in 2 square slots along each side of the single hung window, tell me what its name & number.
Thank you.
Regards,
Albert
