looking for window parts

Question

I need a 440/540 Double Spring constant force device and a drum as shown in the picture.

The drum inner diameter is 3/8", the outer diameter is about 11/16", and the length is 1/2".

Can you tell me the part numbers if you sell them? Thanks.

Hello,

This appears to be an older version of our 15-180 balance shoe, which works with the Series 190 coil spring. Take a look at these products and the items under the related items section for all of the replacement hardware you might need. Thank you!
