Coil Balance Replacement

Question

Some of my windows have missing or broken ballasts. Consequently, the windows won't stay up. I believe the windows are Louisiana Pacific.

Attached are the pictures you requested.
The ballasts are actually 3 coil - not 2 coil as I originally stated.
The window in the picture is 32" x 33 1/4"
Side labels from some of the other windows also included.
Please let me know if you need any more information.
Thank you...

See our 15-199 Pivot Shoe, which uses either 1/2" thick Series 160 Coil Balances, or 3/8" thick Series 165 balances. You'll have to remove your old balance assembly from the window and compare the coil spring thickness to confirm which type you need. There's only two ways to choose the spring weights you need: either go by stamps on the springs themselves, or, if there are none or you are unsure, give me the exact weight of the window sash. I can then work out what you need. For removal and replacement details, see the video below.
