Finding the right block and tackle for my double hung tilt windows

Hello,

This looks like our S795-26 channel balance with a 26C strength option. One difference you'll notice is that ours uses a screw tap at the end of the pulley instead of the hook shown on your balance.

You may be able to use our stock balance if the hook on your balance installs in a square cutout that will fit our 26-200 screw plug. If not, we can custom make balances with a hook instead of a screw tab but we'd need to know how many you'd like to order. Please let us know how you'd like to proceed. Thank you!
