17 2 KQ CALDWELL replacement

Question

Hi,
I need help identifying replacement window channel balances. Here are the details:
- Original stamp: 17 2 KQ CALDWELL- Channel length: 18 inches- Channel width: 1/2 inch (across open front)- Channel depth: 9/16 inch (0.55")- Top fitting: winged bracket- Bottom fitting (shoe): triangular with wings, 1 inch depth (heel-to-toe)- Window sash size: 19.5" x 21.25", double-pane glass- Estimated sash weight: 20-30 lbs (glass + frame, not weighed directly)
Based on the fitting style and depth, I believe this may be your Series 380 or 385 channel balance, but I'd like your confirmation before ordering, along with the correct weight-range suffix.
Thanks for your help!

Hello there. This looks like either an S380-18 or S385-18, depending on the shoe depth. See below. Measure your old balance's shoe depth to see what matches best. For a stamp option choose 1720.
