Sash guid?

Thanks for posting! Your exact top sash guide is no longer made but our 18-066 5/8" Nylon Sash Guide may be worth considering as a suitable alternative. Although, I cannot make any guarantees. Your sash has a specific type of contour in it that may prevent this top sash guide from installing. 

Carefully review and compare the dimensions and design below to determine if this could possibly work for your repairs.
