boot for a spiral
It's tough to tell what you have from a broken shoe, but the design of this part is similar to our 15-188. Look this over and see if it would make a good replacement. Take special note of the thickness, which is one of the most important dimensions. Height doesn't matter too much.
You definitely want to compare our diagram to an undamaged version of your shoe. The cam is missing off of the one you have here and that's a very important detail.
That cam actually looks like a different style, so I'm not certain that the 15-188 is what you want. The style of this cam is more like what we have on the 15-129, however this is 9/16" thick. Consider this shoe and see if it would be a better match.
I highly recommend using an undamaged pivot shoe as a reference. In my experience it's never a good idea to base your decision off of a damaged part, there are just too many important details that are lost along the way.
It uses a 31" spiral balance.
Hello,
It looks like this is the same pivot shoe shown in your post from 2021 above. If so, the 15-129 shown in Tom's last response would be our best replacement option. Take a look and see if this could work for your application. Thank you!
Does it look differently shaped when compared to item 15-129?
Is it possible mine contains a narrower mouth while yours is wider, on a narrower channel while mine is a longer channel?
Unforutnately, we can't determine the exact size of your pivot shoe cam based on your photo. With that being said, it would help to see the pivot bar that engages with your cam removed from the sash to determine if it would be compatible with one of the pivot shoe options discussed in this thread.
