Need balancers

Hello, thank you for posting,

It appears that your window uses tilt spiral balances. You could either have the 3/8" diameter tube Series 900 or the 5/8" tube Series 600. The original will need to be measured to confirm the best fit! 

If a new pivot shoe is needed, the original will need to be removed and measured. To move forward, please provide written out dimensions of the width and thickness of the shoe. From there we can compare to our selection to determine the best match. Thank you!
