1/2" Wide Coil Spring

Same issue, but the spring is 1/2" wide - any idea which one will fit my need?
Same issue, means that the bottom 2 springs broke after 18+ years of service...

We should be able to help. Before we recommend anything, can you show me a photo of the pivot shoe to which this spring attaches?

Will the enclosed suffice? Otherwise, I'll have to take it out again.
To re-iterate: the shoes are fine (they glide & stop). The parts holding the coiled springs are OK. All I need are 2 (or maybe 4, for the top sash) 4.5 lbs. constant-force, 33" in length if I believe the engraved text.

Well it's hard to tell from this angle. It looks like it might be similar to our 15-111, but I cannot tell by just seeing it from the side. Look it over and see what you think. If it is the 15-111, this is compatible with our Series 160 spring.

The sizes I read (without taking the whole darn thing apart, again) are: 1" high x 1/2" wide x ~1 1/8" wide (not 1 1/4").
So spring Series 160, 4.5 lbs. (as the sash weighs ~8 lbs.), looks like a match.
How do we go about finding cost for 2 and 4, then what will be the S/H to Ottawa, ON, Canada?
Thanks for your assistance.

Great! That sounds good to me. All pricing can be found on the S160-4 store page. Shipping cost will depend on what delivery method you select during checkout, as we have a few different options.
