I have a 48 X 29 single pain aluminum window with these spring assemblies.
The measure 30 in not including the end pieces. It has 29 9 JW CMC 11 printed on the bar.
I need two assemblies and the little plastic parts that go on the window to push the spring assemblies down.
This is my first pass at this, but have sent pictures and hope this helps.
I used to live in Pennsville, NJ but moved to Tampa 15 years ago.
Please let me know if I need to do anything more to help get the right stuff.

Hi Wayne. For your channel balances, see either our S380-30 or S385-30. The only difference between these two balances is the 'depth' of the bottom nylon shoe, so compare both with your old balance to see what is the best match. Your stamp option of 29 9 is from an older rating system we don't use, so you'll need to obtain the exact weight of your window sash and match it with one of the weight ranges listed with each stamp option on the product page. For your Top Sash Guide, look at our 18-166 or 18-009. Compare both and see what you think is the best match.
