Locking Pivot Shoes and Bars

Home Owner from Kingsford, MI
I am replacing my spiral balances because they have failed on 2 of my windows. This issue is they continually come free from the pivot shoe, which is a locking pivot. To make sure I fix the problem completely, I thought I would replace the pivot shoe with the spiral balance, however, I haven't found a shoe that seems to match exactly. The 15-167 seems to be the closest contender, at the same dimensions as my current shoe. However, I don't know if it will work with the pivot bars I have.

Attached are pictures of the bar and the shoe.

I noticed on my spiral balances that the tube goes longer than the bushing. The visible tube measures 27 3/4" and extends a 1/2" beyond the bushing. So, should the balances be 27" long or 28"?

The tube likely just has worn down or warped over time. Going by the entire tube length and diameter should suffice. 

Now, as far as the pivot shoe goes, could you remove it and show us a clearer picture, and also provide the exact width and thickness? Those are the most crucial dimensions for finding a replacement. To see how to remove and replace a pivot shoe, see the video below.

All measurements are taken with calipers. 2.03" tall at the tallest spot, 1.23" wide, 0.58" at the thickest spot (at guides and locking shoe) and 0.53" thick at the remainder of the body.

The company that made your window balance system has gone out of business. To repair your broken parts, you can use the 15-129 pivot shoe. If you need a pivot bar, use the 26-415. For the window balance, you can use our S600-28. Please note our balance tube is metal not plastic. You should weigh your sash to get the correct balance strength.
