Searching for 31 5 kv cmc 2

Thanks for reaching out to us! We should be able to help with this. I just can't get a good look at your balance's top fitting from these photos which is a very important detail. May I see closer photos of that? 

Thank you very much! This is just what I needed. I recommend our S380-32 or S385-32 channel balances with the 3150 option. Measure as shown in the image below and see which Series best matches what you have now.
