Sash window replacement parts
If the outer tube of the spiral balance is indeed 5/8" in diameter and 42" long, then see our S600-42. To know what color tip to select, obtain the exact weight of the window sash, then match that weight with either color tip option as listed under the product description. Let me know if the weight does not fall in the weight range for either option.
For the pivot shoe, I am not certain that this is the 15-015, which has a characteristic shape--the cam color with these pivot shoes doesn't necessarily indicate anything. Your best bet is to remove the shoe and compare its width and thickness to options like the 15-046, 15-047, or 15-118. See if one of these match up.
