Non tilt window

Question

Old vinyl windows, no make info found.  Cannot determine the series of the channel balances .  One piece is stamped A2220 (photo).   1/2" x 23".

Jasmine · Accepted Answer

This balance is assembled with a wingless top guide and a winged balance shoe. To replace it, you'll need the S350-23.

The 2220 stamp will support a sash weighing 8 to 13lbs. You may want to double check that your sash weight falls between this range.
