Hey, Jim. It sounds like the S190-540 is not strong enough. How many of these are used on each side of the window? Also, what is the weight of the sash?

Hmm... you mentioned that the Series 190 is different than your old springs. That may also be a source of the issue. If possible, I'd like to see a picture of the pivot shoe to which the old springs attached. I would also like you to confirm the weight of the sash. Five pounds is exceptionally light, and considering two S190-540 springs can carry 5 pounds each, your window should actually be hard to close instead of not being able to stay up.

Thanks, Jim. I think it'd be best if we see pictures before you buy anything. A lot of our coil balances look very similar with only subtle, but important, differences.
