CRL ALUM-FA2930GW-VCP-1 2930 Channel Balance

Hello,

It looks like you have either our S351-31, with a 15-002 bottom attachment, or S390-31, with a 15-001 bottom attachment. Take a look at the image below to determine which balance you'll need. 

You'll also need to locate the stamp code printed on your 31" balances to choose the corresponding spring strength options for your replacement balances. Thank you!

Comparison of the S351 and S390 balance shoes.

The 27" versions of these balances would be either the S351-27 or S390-27 but you'll still need to measure to choose between the two. 

Also, please note that 2930 would be for a 30" balance. The 27" channels should have their own stamp that you'll use to choose the corresponding strength options.
