Replacement part for a constant force coil counter balance.

A quick learner from Albertson NY says:
I was told by the dealer that it was an Acuweld double hung coil constant force counter balance. The coil snapped and I'm looking for a replacement. It has 7R printed on the body.

Thanks for posting! I believe you should consider our S140-7 coil balance. Let me know if this is a good match.
