Good Day,
I need to order 12 spiral balances for my tilt windows.
My spiral balance have white plastic tube and not a metal tube.
Is the series 600 spiral balance similar to my old balance (see pictures)?
Thank you,
Spiral balance identification

Hello!
It looks like your outer tube diameter is bigger than 3/8" so you presumably have our 9/16" diameter Series 600. You'll also need to weigh your sash on a scale and refer to the weight chart on the S600 product page to determine the correct strength option for your balance.
