Thank you for reaching out to us. It looks like your balance uses a terminal clip like our S770. Note that this is designed to screw in at the top of the metal channel, so you'll want to make sure yours does too. There should also be a stamp printed on the metal channel that will indicate the strength option needed.

If you need the pivot shoe, take a look at the specifications of the 15-129 and see if this matches up with your old one.

Please let us know if you have any questions.
