The shape may be a little different, but I still think either our 15-001 or 15-002 will work. I'm just not sure which one. Between these two shoes, which is closer to your own measurements? Personally, I think it's closer to the 15-001, but you should measure yours just to be sure. Keep in mind your measurements may not be identical due to wear, so use your best judgement.

Yeah, it sounds like the spring strength might be mismatched. What is the weight of your sash and what option did you select when you purchased your balance?

Hmm... 2140 should be able to support that weight, though I admit that 15 pounds is right on the cusp.
You mentioned that the original stamp is C21. That may be something like a 21C stamp, which corresponds to our 2130 option. Weighing the sash itself is usually better than relying on the stamp, but in this case I think maybe going down to the original 2130 spring strength is your best bet. Also triple check your sash weight just to make sure its not a less than 15 pounds. |
