Nuair side window alide

Thanks for posting. Nuair windows often use the Series 385 Channel Balance, which have top and bottom fittings with wings and a shoe that is 1-3/32" deep. See the illustration below for reference. If these details do not match what you have, please send closer pictures of the fittings on your old balance, and measure the shoe's depth, and we'd be happy to find something better.

Close up view of the S385 balance shoe.

Assuming this is a Series 385 however, go with the S385-25 with a stamp option of 2440. Let me know if you have further questions.
