Assistance to get the right parts

Hello,

The S600 is actually 9/16" in diameter, which is considered 5/8" in the trade. Based on your photos, I agree that the S600-29 would be our best match. Since there is no colored tip visible in your photos, you'll need to weigh your sash and follow the chart on the balance product page to choose the correct color for your replacements. 

How to measure the tube length of the S600 spiral balance.

As for the pivot shoe, the 15-047 is thicker than the measurement shown in your photos. The 9/16" thick 15-118 looks like it might be a better option to replace your discontinued pivot shoe but we would like to see photos of your pivot bar removed from the sash to confirm if it would be compatible. As mentioned in our product description, the cam slot has a center tooth and an overall measurement of 5/16" wide and 3/16" high. As long as your pivot bar would fit those measurements, I see no reason why it wouldn't work for your application.

Your til pivot resembles the 26-361, which would fit the 15-118 cam opening. If they need to be replaced, you would need to drill out the rivet while being careful not to hit the glass inside the sash. You should be able to reuse them as long as they're still in good shape and have the same tip measurements shown below.
