Block and Tackle and Spring 27"

Question

Hello.  I was trying to find two of the springs in the photo.  Not sure if they ever had wings or not as they could have ground off.   I would need 2 of these '2640'. I also have 4 similar ones but they ate '20' lb ones (27")  I also need one those spring clips that you set when you being the window up.  Thx in advance for any info.

Looks like you have either an S351-27 or S390-27, depending on the bottom nylon shoe depth. You'll need a stamp option of 2640, which supports a window sash in the weight range of 19 through 26 lbs. If you need new take-out clips, see if our 16-002 matches up.
