Kinro window balances 45"x47"

Hello,

Most Kinro windows use Series 385 channel balances but you will need to confirm that the 1-3/32" depth of the bottom fitting matches yours. If so, there should also be a stamp code on the metal channel that you'll need to choose the corresponding strength code for your S385-21 replacement balances. Take a look and let us know if you have any other questions.
