these are pictures of the old balance and one of the new ones I have ordered from you (3800). I have successfully installed 4 (2 windows) however it was very tight. On the 3rd window, I cannot fit the window back into the sash with the new balance installed.
when measuring the depth of the 2, the old one measures 1/2 inch and the new one is thicker measuring 5/8". I thought this might be the reason it was making the window fit tight in the 2 and not at all in the 3rd. also on the shoe and the top piece, i noted that the wings on the new one is thicker than the old one.
I have been discussing this with Steve and these photos follow up our conversation. In picture 1 you can see the 2 laid on they're side and see the difference in the depth of the 2 (new one is 5/8"). I'm closing on this house in 2 weeks and this is one of the things I promised the buyers would be fixed. ...Rick
