constant force balance

Question

these are tucked in a very tight space. We have to separate the 2 pcs in order to change them out.

Thanks for posting. This pivot shoe looks like our 15-087; but please compare the width and thickness with your old shoe to affirm that these critical dimensions match. Furthermore, your old shoe's cam looks very different. Could you show us a picture of the pivot bar that fits into this shoe, preferably out of the window? Knowing its dimensions, especially the distance between the center of each mounting hole and the tip that fits into the shoe, would also be most helpful. That way if we determine you need a different pivot bar, we can try and recommend something for you.

The 15-087 is compatible with our Series 180 Coil Springs. The spring you show in your photos is stamped '10', which indicates a 10 lb spring weight. We have no coil springs with that spring weight, but you could use (2) of the S180-5 5 lb springs instead. See our 15-086 Tandem Coil Housing for extra housing, as well as our 16-024 Mounting Bracket to replace your old metal bracket. Let me know what you think.
