Window Balance Replacement - 36" - 35DS 35

A handy person from Jupiter, FL says:


Am in need of replacement 36" window balances stamped 35DS 35 for Lawson SH-7700 hurricane impact windows. Track measures 1/2" and both top and bottom guides are winged (pictures are attached). Given this:

1. It appears top guide 19-005 and bottom shoe 15-005 are needed. Can you pls help confirm?

2. If so, I believe series 380, option 3550 would be the best product to match stamping on existing channel and support the sash appropriately?

Thank you for your help,

Thanks for writing in. This looks like a S380-36 Channel Balance. Your stamp code of 35 DS 35 is for a 35 lb sash; you can get the exact weight of your window sash to confirm this. If that's the case, you can use our stamp option of 3550, which is for a window sash in the weight range of 30 through 35 lbs.
