Replacement parts for double hung windows

Question

Hi. I'm trying to locate replacement springs and sliders/units for 2 American Heritage(?) double hung windows approx 15 years old. Photo 937C? shows a snapped spring and has 8HB stamped just below the 2 holes that connect to the side bracket in the track (photo E0CA?). The housing unit attached to the window doesn't have any markings (photos 5AB2?. And 346C?).

There is no obvious way to remove the sashes - they will tilt forward but they don't seem to tilt at an angle to remove them from the track (as in your video).

There is a screw on the underside of the lower sash (photo 35C9?) that may be related to the spring holder but I don't want to remove it yet without some advice. Also the track doesn't have a wider gap/space anywhere as shown in the middle of the track in your video to slide out the spring housing unit

I'd be grateful for advice if you havereplacement parts for the windows and how to replace them.

Hello,

I can't be sure but your photos resemble the 15-087 housing pivot, which uses the S180 coil springs and other related items from our product pages. The part that attaches to the bottom of the sash with screws is the pivot bar, which you shouldn't need to replace unless it is broken.

See our video below that shows how to make a cut-out in your window jamb to remove and replace the original hardware. We've also related a few additional videos on this page to assist you. Thanks for posting.
