Trying to make sure I order correct balance parts

Contractor from Indianapolis IN
Have tilt windows, metal tube length is 28.5 so should I round up to 29 when ordering.? Definitely 3/8 width. No idea on window manufacturer original vinyl windows from when house was built in mid 90's. The only identifier on existing spiral balance is in the one photo it says "EOB". Thank you.

Hey there!

This looks like a tilt spiral balance. If the diameter of the outer tube is 3/8", see the Series 900. You can round up to 29" as well. Let us know if you have any questions!
