Coil balance and shoe replacement
Hello! The pivot shoe for your first window appears to match our 15-199. This is compatible with two different coil spring sizes: the 3/8" thick Series 165 and the 1/2" thick Series 160. We also sell a cover for each size: 15-204 for the 3/8" and 15-150D for the 1/2".
Your second window appears to have a pretty typical tilt window spiral balance. It is likely our Series 600, which has a 9/16" diameter tube. We also sell the Series 900 with a 3/8" tube.
As far as the spiral balance, can you tell what kind of shoe it is connecting to?
Your exact shoe isn't made anymore, but we have a ton that could potentially replace it. It will ultimately come down to its thickness. If you can give me that measurement, I can give you a part number. In the meantime you can see our whole selection here.
Do you have something like the 15-015, but one that is more narrow than the 1 1/4" and has the same hole size for the pivot bar to go in?
Nothing comes to mind, but "more narrow" could mean a lot of things. Your only hope of finding a good match is to get precise dimensions. You need the hard numbers, estimations just won't do in this case.
Any ideas?
Sure, a few shoes come to mind, but I have to stress that you need to get precise measurements. Just knowing that it's bigger isn't enough, we need hard measurements. For example our 15-173 shoe looks similar at first glance, but I don't know how our dimensions match up. The hole in the cam is designed to accommodate a 3/16" high x 5/16" wide pivot bar. What hole size do you need?
This product is a good place to start at least, but let me know if any of the measurements I mentioned, or that you see below, differ in any way. If they do then I need you to tell me exactly how.
Thanks for confirming. That's actually a pretty peculiar size. It doesn't seem that we have anything that matches. You may want to triple check that just in case. The 3/16" high x 5/16" wide measurement I gave you before is only 1/16" off in either direction from what you gave me. If you have a more accurate measuring implement that shows you sixteenths, I recommend using it here just to be safe.
