Length 14 inches. Width 1/2 inch channel balance

Thank you for submitting your inquiry to our discussion board.

Based on your pictures, it looks like you have either our Series 380 or Series 385 channel balance.

The difference between these two balances lies in the bottom shoe attachment.

Comparison of 15-004 and 15-005

The series 385 balance has the 15-004 shoe which is slightly larger from front to back, as illustrated.

If you measure your shoe as it is pictured here, you should be able to determine which one you need.

Once you determine the series, you will choose the 14 inch balance and 1320 option.

Please let me know if you have other questions.
