Hello,

For the top sash guide, you may need the 18-044. Take a look and compare the measurements below to yours.

For your 24" window balances, see the S390-24 with (2320) strength options for a sash weighing between 9-15 lbs. Thanks for posting!

From your 1st picture my top sash guide is 1/2 inch wide. Top to the hole is ok.
2nd picture my top sash guide is 1 5/8 inches tall 3/4 inch wide and 11/16 deep.
My window balance top plastic piece seems to be cracked. Otherwise it is the same as the one in your picture.
Please help me get the right parts for my window.
Thanks,

Thanks for getting back to us with your dimensions. It seems like the 18-029 may be a better fit. Review the specifications below and see what you think.
