Perhaps I can be of assistance. Regarding the broken window balance, we need to see the top and bottom nylon fittings attached to the metal channel to determine the series. Also, it's important to note that your stamp option of 3050 tells us the metal channel length should be 31", not 27". Please recheck the dimensions. As for the top sash guide, look at 18-008 and compare to an unbroken one. |
