Sash Spring for Aluminum Window with Tilt-out Sash

A home owner from Gulfport, Mississippi says:

August 8, 2016

The "tube" seems to be a white plastic, with the coiled spring assembly inside. The upper screw mounting broke off and the spring now doesn't work, as a result. The white plastic tube is about 28 1/2 inches long. The length overall, from the upper broken end to the bottom of the steel extension which has the 2 steel pins, is about 30 5/8 inches. The little plastic tab above the bottom (which has the 2 steel pins to secure the bottom of the assembly) seems to be light yellowish---don't know if that means it was white and has yellowed over time, or that is a very faded light green. Tube diameter is about 3/8 inch.

Thanks for posting! Based on the size of your tube, I think you could use our S900-29 spiral balance for tilt windows. It's 1/2" longer than your old one, but you should have enough play. It's better to be slightly too long than slightly too short, if you can't get an exact match. As for the tip color, I can't say for sure. I think you might want to weigh your sash on a scale to confirm the best match. We have a chart on the S900-29 store page that tells you how much weight each option can support.
