I'm afraid we can't say for certain. I would imagine these were all originally installed with S-clips but someone did a very half-hearted repair. However, that is an educated guess. It appears you should be able to use the same S-clip but our 19-029 may also be worth considering. It's normal for springs to be the same size for the top and bottom sash, assuming that the sashes themselves are the same size. However, if the top and bottom sashes are of differing sizes then it's a little odd. I hope this helps. |
