Spiral Balance and shoe

Hey there Joe!

Thank you for reaching out to us. If the tube is 3/8" in diameter, I recommend the S900-29. We don't have a black tip option though so you would have to weigh the window sash on a scale to determine the proper tip option.

We have the S600-29 with a black tip but this is 9/16" in diameter. You could always double-check to be safe.

As for the pivot shoe, can you write out the thickness and width? It's hard to read accurate dimensions from photos of a tape measure so we'd just like to be sure. 

We believe you can use the 15-212 pivot shoe. Have a look at the specifications and see what you think.
